[opendtv] Re: HD DVR for the antenna crowd

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

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."
