The $29 Snow Leopard upgrade: usable for 10.4 Intel Macs as well?

I bought the $30 snow leopard disk and upgraded 100% from 10.4 to 10.6

The following month, I bought a 500gb harddrive for my macbook and did a free install of 10.6

The $30 disk is proven to be an upgrade from at least 10.4 and a full install if being used on a new internal harddrive.

Does anyone know if I were to use the $29 Snow Leopard upgrade to update from Tiger, will my old iPhoto and iMovie still work or would they be broken?

I have all my videos on iMovie 06 HD and the DVD versions on the 06 version as well. I bought a Snow Leopard mac enticed by previews of iMovie 09, only to find it's dumbed down. So now stuck with files on an overburdened g4. I am pretty sure I loaded iMovie o6 HD on the new Mac, but then the iDVD 06 files wouldn't even open, and were supposed Locked (this option was not checked off on the GetInfo box.) I uninstalled iDVD 09 and reinstalled iDVD 06, hoping then to use it for the iMovie HD. Surprise, error message saying that the iDVD 06 would not even work with Snow Leopard.

So, all my iDVD projects are stuck on the old G4 with Tiger? is there a third party program to make iDVD work in SL? or should I load Tiger on a partition in the new Mac (not something I've done myself, but will get someone to do it, I guess...) Is that my solution? At least I'd have a more power computer to work on the old videos.

If this is an example of Apple's innovative thinking, then I wish I had never abandoned Windows. Well, I haven't actually, and do my HD editing on Vegas, but so much early stuff is in iMovie.

@Tony:

Format? That sounds like a clean install (aka "erase & install") rather than installing over Tiger. No?

How to install over tiger:
1. Make backup of data
2. Boot off of the DVD holding down option at startup. (yesh it is bootable!)
3. Open Disk Utility, format the hard drive as Macintosh Extended Journaled
4. Install!

Because iLife '09 requires Leopard, so if someone only has Tiger and bought iLife '09 all they get is a pretty box.

Here's the big problem I have with the idea of requiring Tiger users to buy the full pack with iLife '09. What about people who already bought '09? Apple's forcing them to buy it AGAIN? True there's also iWork included, but not everyone would have a use for it and would consider it a waste of money.

It works as an upgrade from Tiger. I have it. I have done it. It works.

Does anyone know if you can install Boot Camp with the 10.6 Snow Leopard disc, or does that still require the 10.5 Leopard disc?

How do you know this violates the Snow Leopard license agreement? I took a look at Apple's software license website page (http://www.apple.com/legal/sla/) but did not see the license agreement for Snow Leopard listed.
