Tiger's QuickTime Misperforming on an iBook G3?
November 2, 2005 8:35 AM Subscribe
Ever since upgrading to QuickTime 7 and Mac OS 10.4 (Tiger), I've noticed that apparently what I think is the H.264 and H.267 codecs play very choppily on my machine.

The audio track doesn't freeze, but the video stops, then moves forward slightly choppily, then goes forward, then repeats the cycle a few seconds later, making the resulting video mostly unviewable. I've noticed this specifically on videos from the iTunes Media Store and Apple Movie Trailers.
My machine isn't horribly ancient, but it's not top-of-the-line, either: an 800 mHz iBook G3 with 640 MB RAM (which is the maximum available for this unit). I know the G3 is at the hind end of the pack nowadays, but I can't believe it's been entirely ignored when these codecs were tried out at Apple.
I have tried three things: increasing the QuickTime cache (no effect), reducing the number of open applications at the time (very little or no effect), and letting the whole video load before trying to play it (very little or no effect).
Any help would be appreciated. Thanks.
