I've got my TV running at 1280p already; it seems to work quite well for 
regular tv. Will that not be the case for playing HDTV-encoded programs?

All I had to do (for dvd rips, haven't actually used a disc to playback in 
a long time) is change the mplayer options to include '-monitoraspect 
16:9'; works quite well here.

AC-3 works fine for DVD rips for me; is it a different case for HD 
playback since it's handled by Myth's audio layer?

Thanks again for the list!
