I'm going to take a stab that you're watching standard definition video
on your 16:9 screen via MythTV and it's not 'stretching' it to fit.  Do
your DVD videos display properly via MythTV on the 16:9 screen?

There are something like three places to check on the system:
o Your X server configuration to make sure it is set to properly display
on a 16:9 screen (depends on your graphics card, but if it is nVidia,
check out:  http://www.mythtv.org/wiki/index.php/ComponentOut
o Utilities/Setup -> Setup -> Page 2, under "Monitor Aspect Ratio"
select "16:9"
o Utilities/Setup -> Setup -> TV Settings -> Playback -> Page 1,  check
out  the "Aspect Override" option.  If you want everything full screen,
set this to 16/9.
