Make sure that  your xorg.conf file only allows 1280x720 as a mode.

I have posted my xorg.conf so if that is of interest, look in the 
archives.  The point is, don't let xorg send 1080 stuff to the TV and 
then have the TV take it down to 720.

Also, on audio, with something like mythbuntu, make sure you don't have 
a asound.conf file or the one that ends in rc  and that you don't have 
pulse audio.  Just let the default settings handle it.

Let me know if I can be of more help.
