[ivtv-users] hvr-1600, frame CRC mismatch - incomplete frame

[Kyle Lil]

That's correct. The card is connected to a ClearQAM cable source. 

The cable is split once between the wall and the tuner card. There is about 15ft of cable to the wall and I live on the 4th floor. I wouldn't have guessed that signal strength would be my problem, as it seems to work OK in Windows or if I plug the cable into the QAM tuner on my TV. Does 0145 seem like a reasonable number for signal strength or SNR? I'm not sure how to translate that into % or dB...
