My MacBook has QuickTime X on it, and when I play videos directly from Apple's website (such as the latest Keynote: iPhone OS 4), things start pixelating, audio becomes choppy and the video overall just lags. Why?

That's my only question. Why?


I found QuickTime 7 for Mac OS X 10.6 (which gets downloaded to the utilities folder). Here's the link if anyone actually needs it:

KBDL923: QuickTime 7 for Snow Leopard

In any case, the Keynote runs better.
