Turns out that you were sort of right. My TV can handle video and PC
levels. I had it set to autodetect. Something has changed in either
MythTv, minimyth, or the nvidia drivers to cause my TV to start
misrecognising video levels as PC levels. When I explicitly set it
to video levels, picture is back to perfection. :-)

Thanks for help,
