Just a thought, maybe try exporting the EDID (from nvidia-settings)
while your Myth system is directly connected to the television, and
then configuring X to use a customEDID once you're going through your

I noticed that when switching over to pass-through (I have a Sony
receiver) the EDID was reported differently in the X log file, I
assumed it was because the card was now interrogating the receiver and
not the TV.

This may be totally bad advice but if you're looking for things to try
it might be worth a shot :)
