I don't really remember how it was before I upgraded to Tiger, but now i'm trying to watch the latest Apple event video and even though the "quality" is 100%, I'm getting 2-6 fps and Quicktime player is using basically 100% of CPU time. Playing other types of videos (not h.264) is fine. Specs: iBook G3 800; 384MB Ram; latest versions of tiger and QT. So does anyone know if this is normal or not? Also, where can I DL some of those keynotes (the h.264 ones) so that I don't have it stream and decode at the same time?
