I have to retract that. It turns out that there is some strange interaction
between the cabletv box and the card. When I rebooted into 'my' patch
I still got the noisy signal. I then power cycled the cabletv box, and
voila,
I got a good signal on my own patch.
Awfully sorry about this. After having had the familty sit in and check
the differences,
I must say that the patch does not fix the issue. This time around I
have x11grabs with
ffmpeg to show if you want.
I'll be away from the card until the end of the coming week. Then, I'll
bring out the multimeter...
Best regards,
