I had this exact same problem with my projector.  Your device is 
reporting the resolutions it is capable of receiving and not its native 
resolution.  Myth then picks the highest resolution supported, which is 
wrong and in my case looked terrible.

I think you need to have an xorg.conf file and just limit the resolution 
to the LCD TV to its native resolution.  I posted that on another email 
but here are the relevant sections (several have been edited out of this 
email):

Section "Device"
