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 lossless
mode, but not at a bitrate that would fit on either blue laser format.

Uncompressed hd is 1.5 gb/sec. DVDs and HD-DVDs and BluRay are all
MPEG-2

Actually, "by definition" is a bit strong. I have never seen any
mechanism
in the MPEG-2 specification and annexes that would permit
transmission of
uncompressed audio or video. I'm only making the assumption that "no
mechanism" means "only compressed audio and video."
