    Well, downloaded the Public Preview of Apple's QuickTime 7 for Windows from http://www.apple.com/quicktime and wondered how their new MPEG4 / H.264 enabled version would do with their HD 1080p demo videos on my AMD64 4000+ and ATi FireGL V7100 workstation graphics card.

    Ran serenity_1080p.mov in a 1920x812 window (it's a 2.35:1 trailer) so no scaling involved on my 2560x1600 resolution monitor. :D

    The titles, beginning and end and titles pieces (e.g. "from the creator of Buffy") and 'Serenity' logo are pixel-sharp and take about 66% of my CPU power, but the actual movie parts take 99% of CPU and start skipping like loopy-loo on a frosty morning.

    Looks like either Apple need to do some more work or we need new ATi R520 chipset with it's hardware H.264 decoder because this is not low spec kit and it appears that it can not handle decoding this format in realtime.

    Got 2GB of super fast RAM, plus 10,000rps SATA drives too ... so don't think hardware is the issue here ... looks like this is intensive CPU use. :eek:

    Interesting, trying to get some other trailers here to compare and having trouble downloading them on WinXP; and my Mac only streams them, doesn't download them from quicktime.com site. :(

    Just watched the Steve Job's keynote speech http://stream.apple.akadns.net/ and QuickTime 7 performs really well ... stopping and starting streaming anywhere is cool; as is the scaling, ran that stream at 1024x768 and it looks pretty good.

    dvdmike007, are you nVidia or ATi for graphics?

    PS: View Source on the Apple pages gave me the links to download HD files directly :)

    I'll give it a go on my nVidia 6800 Ultra PC and see if that makes a difference, may help eliminate if it's AMD/Intel or ATi/nVidia issue.

    66% of four 3GHz processors (two virtual time two physical) is 264% of a single processor. :eek: If it takes that to run smoothly, they definately have some optimisation to do, and it's no wonder that this is a "preview" (read beta).

    I was pointing out that dvdmike007's PC of "2x 3.0666 intel xeons" is in effect (with multi-threading) four 3.06GHz Intel Xeon CPUs running in parallel. If H.264 1080p decoding takes 66% of that processing power then it's a resource hungry puppy!

    My HTPC has a single AMD XP 3000+ and GeForce 6800 Ultra in it, whilst my desktop has a single AMD 64 4000+ and FireGL V7100. Neither of which seem to be loving QuickTime 7's H.264 1080p demos and trailers, but then again neither does my G4 powered Mac Mini.
