What is about DVDs that only allow them to read certain formats?

    And would a higher then 720x480 video work on DVD as long as it was a bitrate the dvd player could handle?

    The decoder chips are designed, generally, for MPEG-II at MP/HL. (Or is it MP/ML? It's been a while,) which specifies a variety of picture formats

    Also, I suspect that they generally only have one or two specific crystal sets for generating PAL, NTSC, or NTSC progressive or PAL progressiev. (Obviously the upscaling players are different animals.)

    It's not in the specs. There are a handful of DVD discs out there with HD content encoded in VC-1 (WMV HD), but they obviously are not playable on standard DVD players.

    DVD just doesn't really have the bitrate capability and data space to handle HD, which is why HD-DVD and BRD are on the imminent horizon.

    Except that you asked a question about it. There's your answer.
