We're back with another edition of Ask TUAW. This time around we've answering questions about iTunes libraries, Mac data recovery, Snow Leopard on older Macs and more.

As always, your suggestions and questions are welcome. Questions for next week should be left in the comments. When asking a question please include which machine you're running and which version of Mac OS X (we'll assume you're running Leopard on an Intel Mac if you don't specify). And now, on to the questions.

Daneel asks:

I'm running OS X 10.5.7 and Windows Vista (via Bootcamp) on my iMac 24". I was wondering if there was any way in which I could make the iTunes apps in both Windows and Mac use the same iTunes library. File access is not a problem as I've got the ntfs-3g driver on the mac side and mac drive on the PC side.

I have my iTunes library on an external hard drive. To make iTunes use this particular folder, I create an alias of the folder on the external drive and replace my iTunes folder located in Users> "User Name" > Music with the alias. iTunes has no problem with this setup.

You should be able to do the same thing in both the Mac and Windows versions of iTunes. Just set an alias of the iTunes folder you want to use in Windows pointing to your Mac iTunes library and you should be good to go.

"A rose by any other name would smell as sweet." - William Shakespeare, Romeo and Juliet

If we applied Shakespeare's logic to today's digital age, then it would also mean that watching mis-tagged or untagged videos on your Apple device (be it a Mac, iPhone, iPod or Apple TV) would be just as enjoyable. Okay, you got me, they'd probably be just as good. But this doesn't mean you're excused from tagging your videos appropriately.

First, a bit of background. The vast majority of videos purchased from the iTunes store, as well as "digital copy" (iPod/iPhone pre-formatted videos that are sometimes included on DVDs and Blu-Ray discs), will come pre-tagged. So, the situation for those in this camp (myself included) is peachy, especially when using an Apple TV. Your videos show up on the screen screen with proper titles, season and episode numbers, actors, and descriptions. Just the way Steve likes 'em.

But what if you already own the DVD and want a version for your iTunes library? For those of you with the time and patience to rip an MPEG-4 version (and believe me, this takes some patience, especially if you use H.264 encoding) of your favorite videos, a HandBrake-MetaX martini make tagging your videos a bit more of a pleasurable experience - as if it wasn't fun enough already.

Controlling your music while you're working (or playing) on your computer should be virtually seamless. While these days it's almost impossible to buy a keyboard without media keys built-in, there are many users that either don't have media controlling keys on their keyboards, or would simply prefer to keep their hands on the actual keys. While iTunes is not capable of assigning hotkeys on its own, there are a number of iTunes controller applications on the market that can add this functionality.

In my opinion SizzlingKeys deserves to be at the top of the list of iTunes controller apps for its simplicity, reliability, and extra features. SizzlingKeys installs as a preferences pane, and has a very intuitive interface that allows you to choose which functions to enable, and what the hotkeys should be for those functions.

The list of things you can control with hotkeys is fairly comprehensive:

• Play / Pause
• Previous / Next Track
• Volume Down / Up
• Mute / Almost Mute
• Show / Hide iTunes, Playlists, Search
• Set song rating
• Show floater (song information)

In addition SizzlingKeys offers some non-iTunes "extras" that you can control:

• Sleep computer
• Lock computer
• Activate screen saver

The standard version of SizzlingKeys is free, but there is also a Pro version for $5 that includes the ability to skip forwards and back by a customized interval, the ability to toggle shuffle and repeat modes, and the ability to control the system volume.

Yesterday, Apple released MobileMe Control Panel for Windows 1.4, recommended for users on corporate networks that use proxy servers.

Some users were reporting errors when trying to sync contacts and calendars, or were unable to log into the MobileMe control panel at all. This update sorts that out.

According to Apple technical note on the subject, supported proxy server types include:

• Web proxy servers (HTTP)
• Secure Web proxy (HTTPS)
• SOCKS proxy servers (see note below)
• HTTP/HTTPS proxy servers that require authentication
• Proxy bypass lists
• Proxy auto-configuration (PAC) files

The update is available on the MobileMe website, and is also included with iTunes 8.2 for Windows.

iTunes 8.2 just became available in Software Update. According to the update notes, "iTunes 8.2 now supports iPhone or iPod touch with the iPhone 3.0 Software Update. iTunes 8.2 also includes many accessibility improvements and bug fixes." The update weighs in at 79.3 MB.

QuickTime 7.6.2 and GarageBand Update 5.0.2 also became available at the same time. In keeping with Apple's policy of full disclosure, there's not much information for users about what's in either of the updates, although subscribers to Apple's security notification list got an email with a list of 10 fixed vulnerabilities in the QT update (soon to be posted at Apple's security site and reproduced in the second half of this post).

The GarageBand update "addresses general compatibility issues, improves overall stability, and fixes a number of other minor issues [including] Improved purchasing experience for Artist Lessons in the GarageBand Lesson Store [&] Accessing installed Jam Packs in the loop browser." The update is required if you are purchasing lessons from the Lesson Store.

The iTunes update is one more clear sign that iPhone 3.0 is just around the corner. Be sure to stay tuned to our coverage of the Apple Worldwide Developer Conference next week for all your iPhone news!

Yesterday, Megan noted a Fortune story saying that iTunes syncs flawlessly with the new Palm Pre. This, of course, got the water-cooler talk bubbling: "How did Palm pull it off? Will Apple allow this to happen?"

Turns out they already have. A tech note on Apple's website notes the two dozen or so third-party players that iTunes (for Mac OS X, at least) is compatible with, including Rio and Creative Labs Nomad MP3 players. True, many of the models listed predate the iPod, and the tech note itself was last updated a little less than a year ago. But third-party device compatibility with iTunes isn't without precedent.

Daring Fireball's John Gruber pointed to a story by Jon Lech Johansen that says Apple may block iTunes access to the Pre in a future update; Gruber himself said he "wouldn't be surprised if they did." I'm not so sure.

First, let's look at how it works. According to Johansen, a unique USB device ID allows iTunes to recognize MP3 players (including iPods) that it's compatible with. Johansen speculates that Palm is using one of these IDs when communicating with iTunes. If it's an iPod's unique ID, then it will work with iTunes for Windows, too; this is an important litmus test and we don't know the results yet.

I can understand Apple might not cotton to a Palm Pre specifically masquerading as an iPod USB device. Given that, allowing the Pre to freely communicate with iTunes isn't necessarily bad business sense, presuming Palm implements the functionality in a forthright manner (like other third-party MP3 players that iTunes already supports).

Why limit access to the Pre, aside from pure spite? If someone already uses iTunes, chances are they have some quantity of DRM-free iTunes Plus music on their computer. There's no technical reason why the music shouldn't be easily playable on the Pre. One of the upshots of removing DRM in the iTunes store is to facilitate device interoperability. Allow non-Apple devices to play iTunes music, and suddenly Apple has customers it didn't have before.

If Apple chooses to cut off just the Pre, and Palm is following the rules, Apple is unnecessarily cutting a stream of revenue. That's something I don't see Apple doing lightly.

Update: Our bad... the date on the MacRumors comment was in late April, and this recycled up into our queue due to an editing mixup. Apologies –Ed.

There's a new iTunes beta version out in developers' hands straight from Apple, and a forum poster over at Mac Rumors found a little something fun in the About screen: a reference to Gracenote's ability to identify Blu-ray discs. Gracenote is the service that IDs your CDs when you import them into iTunes, so you don't have to sit there and type all the track names and artist information in. Apparently Apple is mentioning that not only CDs and DVDs, but also Blu-ray discs, will get information from Gracenote in the latest version of iTunes.

This doesn't mean that Apple will adapt Blu-ray as a standard (though it would probably be about time, don't you think?). But it should mean that the future version of iTunes will include Blu-ray support, so if you happen to have a Blu-ray drive hooked up to your Mac, you'll be able to read or play the discs via iTunes.

It could just mean that Apple has upgraded the Gracenote version in their app, however, and that they have no plans to actually use it -- the text in the About screen could just be a boilerplate cut-and-paste from some required Gracenote documentation that happens to include "Blu-ray." We'll have to wait and see just what shows up in 8.2 when it eventually releases to the public.

We're back with another shot of Ask TUAW! This time we've got questions about getting WiFi in an older G4 PowerMac, creating photo contact sheets, blanking a display, automatically opening downloaded files, managing iPhone apps in iTunes, and more.

As always, your suggestions are welcome. Questions for next week should be left in the comments. When asking a question please include which machine you're running and which version of Mac OS X (we'll assume you're running Leopard on an Intel Mac if you don't specify). And now, on to the questions!

Once again, it's time for another edition of Ask TUAW: the place where we try to answer all of your Mac and Apple-related questions. This week we're taking questions about tracking your total iTunes purchases, forcing processes to quit, doing a clean install of OSX and more.

As always, we welcome your suggestions for this week and questions for next time. Please leave your contributions in the comments for this post. When asking questions, please include which Mac and which version of OS X you're running. If you don't specify, we'll assume you're running Leopard on an Intel Mac.

Dima asks:

I would like a way to require a password when the computer wakes from sleep, but not to require a password for just the screensaver. Is there a way for me to accomplish this?

The only way I know of to accomplish this would be to modify the plist file for the screensaver via the Terminal. However, unless this is really important to you, I would not advise doing it. If you want to do it, proceed at your own risk.

Either way, here's the command to enter in the Terminal if you want to try it.

defaults -currentHost write com.apple.screensaver askForPassword -int 0

This will set it so the computer only asks for a password after waking from sleep and not after the screensaver.

Frank asks:

In my finder window, next to my drive's name, there's a number in parentheses. it used to be a (2), but recently it changed to a (3). What does this number mean?

Our weekly interactive podcast goes live on the air tonight at 10pm Eastern time over on the Talkshoe page, so if you're around and ready to talk some Unofficial Apple Weblog news with us, please come by and join in. I'll be hosting this evening, and Dave Caolo will be along for the ride with us, as well as a slew of other familiar names and voices from TUAW and our community. And we'll be welcoming Alykhan "AJ" Jetha as our special guest for the evening -- he's the CEO of Marketcircle, makers of Daylite and Daylite Touch, business productivity management apps for the desktop and the iPhone. Our own Stephen Sande reviewed their products here on TUAW earlier this week.

Also tonight on the show, we'll talk about all of the new iPhone hardware rumors floating around, and try to separate the wheat from the chaff there. There's also rumors of an OS update that we'll try shaking down, and the iPhone 3.0 beta has hit a new milestone, so we'll look that over as well. iTunes prices are up, and sales are down, so we'll try to figure out why. And since this is the eve of the release of Tweetie for Mac, we'll talk about which clients we've used for Twitter on the desktop before and if Tweetie will be everything that everyone else is saying it is. Should be a lot of fun -- tune in promptly at 10 Eastern to give us a listen.

After much time and negotiation, movies have finally come to the German iTunes Store. As of this writing, there are 500 films available to German customers (just about 100 are available in HD), including American hits like The Dark Knight (good movie, but the motorcycle is a bit over the top) and Die Fälscher from German cinema.

Pricing breaks down like this:

• Older titles are sold for €7.99
• Newer titles sell for €9.99
• Brand-new releases are €13.99

Rentals are either €2.99 or €3.99. TV shows came to the German iTunes Store earlier this month last year.

I coulda told you this, though I am a little surprised that we've seen the results so fast. Despite iTunes having put the new tiered pricing into effect just last week, Billboard is reporting that they've already seen sales drop on the higher-priced tunes. The iTunes Top 100 chart has 40 different songs with a new price of $1.29, and one day after the changes, those songs dropped an average of 5.3 places on the chart, while cheaper songs moved up on average. And on the second day of the price change, ten of the tracks that saw their prices rise within 24 hours dropped a huge 12.4 chart positions on average.

Of course, we're talking only a matter of days here, and there are all kinds of things that could have affected this average drop -- lots of the tracks that became expensive were from a Rascal Flatts album, and it could be just that the album has lost popularity, bringing the average down. And don't forget that even though these sales figures may be dropping, they haven't dropped nearly enough to show a loss of revenue (though fewer songs may be selling, they're still making more money).

But for those convinced that higher prices mean lower sales numbers, these first few days of figures will seem to connect all of the right dots. We'll have to wait and see if the long-term effects match up to the figures Billboard has seen so far.

UsingMac has posted an exhaustive look at iTunes from the perspective of making your working life better. From basic tips like shuffling songs and shuffling movies to more advanced tips like using Terminal to set a half-star rating, it's well thought out.

My favorite tip involves browser mode. Many people (in my experience at least) overlook this feature. I find it to be a killer way to categorize and find just what you're looking for, across genres, years, styles, etc. Of course, I'm that annoying guy who gets all excited over tags, charts and graphs, so keep that in mind.
