Hi
I posted this on the ivtv-users list and one of the developers made a
suggestion that appears to fix the problem.
The thread is: [ivtv-users] Distortion on top 1/4 of screen PVR-150
>>There aren't many changes that can cause something like this. In fact, I

I made the change and testing with mplayer for a few hours the distortion
appears to be gone. Ther ghost image I saw before under 0.4.1 also appears
to be gone.
0.5.1 has this same code commented out. So I would imagine making the same
change would help there also.
However mythtv has a new issue with 0.4.1 version of the ivtv driver.
When I attempt to watch live tv the screen freezes after a second and
eventually mythfrontend times out and complains that it has a problem with
the video.

Remote encoder not responding.
ASSERT: "i <= nodes" in /usr/lib/qt-3.3/include/qvaluelist.h (373)
This is slightly different then the timeout I saw with the new firmware.
So I will probably go back to 0.3.8
