What player are you using?

Does the player use XvMC?  Does it use libvdpau?

If you don't use one of those, you probably won't be able to handle
highres decoding.

Certainly playing back 1080i video on my mythtv box scaling to the TV
res works perfectly.  I just play them and mythtv does whatever it does
for playback.  I use an 8600GT card with the drivers installed the debian
way of course.
