BluRay movies have begun switching to VC-1 already, and better yet even MPEG-4 releases are announcedsfu_lifer wrote: ↑In fact, go to the avsforums.
HD-DVD is the winner so far in terms of the movie quality out there. Blu-Ray is still using mpeg2, a decidedly old and crappy compression while HD-DVD is using Microsoft's superior codec. Once Blu-Ray switches over to that, then yes the pic quality should be equal. Blu-ray is 2x larger but they're still having a hard time manufacturing doublelayer blu-ray en masse whereas they've been doing double-layer HD-DVD for a long time now.
