Are These Theortically Possible?

    With the new release of AnyHD-DVD, I was just starting wondering with my being completely new to these new HD-DVD formats.

    But would it be possible using the logic that HD-DVD disk is 15 gigs big, and a SD DVD Dual Layer is 9.7 GB big.

    Would it be possible to actually copy a HD-DVD to a DVDR-DL and play it back on the HD-Player, (this is without changing the compression to that of DVD's format of compression, but leaving the disk as HD-DVD format disk).

    Also another curious question, would it be theoretically possible in the future to rip a BlueRay High Definition movie and then burn this movie image to either a standard Dual Layer-DVD or (better still) a blank HD-DVD disk (when they come out) and watch the Blue-Ray movie on your standalone HD-DVD player. (or vice versa with HD-DVD and burning this to a Blue Ray disk)

    As it seems this High Definition format war would be pointless if this was the case.

    Compressing HD-DVD's would defeat the purpose of high def video's.

    oldjoe Well-Known Member answer your question, yes it is theoretically possible.

    There would be a benefit of DVDs though. They are mpeg2 encoded, and D1 resolution up to 720x576. And, never do they fill the dvd9 space with the menu. Menus, features etcetc reduce it.

    Using the better compression of VC1 or AVC you could author a HD-DVD disc with no menus, special features. You could demux the evob stream and pull out un-needed audio tracks. Even recompress the audio down into DTS or something from AC3+.

    You would end up with something better than DVD for sure.

    And the best thing - a HD DVD standalone would play it, as "HD DVD" on red laser DVDs is supported. (AFAIK this is not possible with Blu-ray, but I might be wrong).

    Its equally possible on BluRay - you just need authoring software for bluray instead of HD-DVD. Bluray players are backwardly compatible. They typically have a legacy dvd optic system too.

    Yes, they can play DVDs. But are you sure they can play HD Blu-ray content from DVD media? Do you have a link to a whitepaper or other documentation?
    Or have you tried it with a Blu-ray standalone Player?
