Jeez... maybe I should just post the same answer to every discussion in this forum...
Apple originally promise MPEG-1, MPEG-2 and MPEG-4 support for QuickTime 5 but they recently announced that it would come at a later time. MPEG-1 is used in VCDs, MPEG-2 is used in DVDs and MPEG-4 is what is often referred to as Divx.
So, QuickTime 5.0 shipped with Mac OS X and Apple recently released QuickTime 5.0.1 for Mac OS 9.X but both will have to wait for direct Mac OS support with an update to QuickTime 5!
