Although I haven't come up with a solution yet, I do see the same problem.

My problem though is that I made so many changes at the same time (new
video card, new MythTV version, new nVidia driver version), and I don't
want to distrupt the system yet, since it's baseball playoff time.  (And
baseball on Fox in HD looks so good!)
