Mudit Wahal gave a great source, the avsforum, I'll elaborate some more in
relation to playback on a MythTV machine...

It does! and Myth can!
Set MythTV up to send the signal (720p or 1080i) that your TV uses as its
native HD mode. If it uses both, I'd suggest 1080i is the one to try and
accomplish), then tell MythTV to output all video at that resolution and let
the software do all scaling. This will scale TV to that output. If you plan
on using Xine or mplayer for DVD's they too will do internal scaling if told
to go fullscreen at this resolution.

Xine has worked marvelously as a DVD player with menu support for many of us.
Its internal scaling and overall video filtering is excellent and with a fast
enough processor which you'll want for HDTV content, it can do excellent
upconversion for DVD's in realtime without problem. I'll even go out and say
Xine will do better than all standalone dvd players, especially the cheaper
models ($2K and under).
