Could you test attached patch?

It enhances reception a little bit, you should be able to receive more 
weak signals.

I was able to made test setup against modulator. Modulator + attenuator 
+ attenuator + TV-stick, where I got picture using Windows driver at 
signal level -29dBm whilst on Linux -26.5dBm was needed. With that patch 
Linux driver started performing same as Windows.
