I used a bunch of these to benchmark different machines and their capability to play back HD content. What I found was that Apple's guidelines for systems is pretty much on the mark. Granted these are using H.264 and not MPEG2 or MPEG4 but I couldn't get more than 12fps on my dual 867Mhz G4, or the 1.67Ghz G4 laptop from work for 720p clips. 1080p was unplayable on both. The 2.0Ghz iMac however cranked 24 fps on all of the above. The one that I found worked best was http://www.apple.com/quicktime/guide/hd/bbcmotiongalleryreel.html which has tons of motion and sound. I also benchmarked recompression of this clip, and a bunch of us on a macaddict forum tested different machine speeds at recompression. you can download 720p quicktime movies from Apple at the HD Quicktime site (http://www.apple.com/quicktime/guide/hd/).
