I was wandering (and just a little lazy to find it myself on internet) what compression your video needs to be in to be right for HD-DVD and/or blueraydisc?

It was a little fuzzy, but I read somewhere .m2t's won't be any good, the files need to be program-streams instead of transport streams. If a conversion like that is necessary, I wonder what the impact on the image quality is (or is it just a header-rearrangement issue)?

Will files compressed with other codecs also work within the HD-DVD specifications and/or blueraydisc specifications? WMV-HD? DivX-HD? MPEG 4? H.264? Cineform (no, I'm only dreaming that...)?

Did you mean m2v's?

Anyway, for video, ISO MPEG-2, H.264/AVC, and SMPTE VC-1 are mandatory for both formats (& 3x DVD ROM). So all players must support playback of them all,
