30GB is not enough capacity for HD-DVD

[HDTV1080P]

In terms of picture and audio quality MPEG-4 and VC-1 is much better quality then MPEG-2. For example if you encoded a move at 28MB per second using VC-1 versus using 28MB per second with MPEG-2, VC-1 would always look better then MPEG-2. The problem we have today is people are using VC-1 AND MPEG-4 at very low bit rates to make the movie size as small as possible. When comparing VC-1 to MPEG-2 at the same exact bit rate VC-1 always looks better then MPEG-2.
Someday studios will stop using MPEG-2. VC-1 and MPEG-4 are much better then MPEG-2 when compared at the same bit rate. I would love to see a 50GB Fifth Element use MPEG-4 or VC1 at a high bit rate. The picture quality would be fantastic.
