Based on your problem description, I don't think that the driver is the
problem. here. It seems that you are experiencing a weak signal. I
too, was experiencing problems like this before I purchased a drop-amp,
but the driver DOES work.
I recommend that you test the card using the windows driver... You will
probably notice the same problems. There is one difference,
however... The windows driver uses DxVA for the mpeg decoding. This
isn't always possible when using linux, due to the proprietary video
drivers out there. :-(
So, unfortunately, I dont think your situation can be helped without
amplifying the signal.
