'Me Too'
Frankly I'd be interested to see if osx can even handle DVD playback on my DV iMac. It seems to struggle with QuickTimes and afaik Mach is no 'realtime kernel' for accurate media playback.
Apple has marketted many of it's machines as DVD ready, I can't see how they can skip support. But.. as I said.. I'd be interested to see if it's even technically feasible.
