More than that...they are almost never MPEG2. Sony's initial releases were MPEG2, but I believe they've switched since then. The majority of HD DVD titles are VC-1, with a small number being H.264.

HD DVD and Blue-ray also use H.264 and VC-1 video. H.264 has a losslessmode, but not at a bitrate that would fit on either blue laser format. Ron John Willkie wrote:Uncompressed hd is 1.5 gb/sec.

I have never seen any mechanism in the MPEG-2 specification and annexes that would permit transmission ofuncompressed audio or video. I'm only making the assumption that "no mechanism" means "only compressed audio and video."
