Highly Ranked

MPEG-4 is much more efficient than MPEG-2, so at a given bit rate MPEG-4 should look better than MPEG-2. That said the more bits the better the quality, until you get to lossless rate that is. MPEG-4 encodes on HD-DVD / Blu-Ray I think average about 15 MB/s so what HBO is doing is still only going to 50% of the quality of those discs. The optical formats can go much higher though.
