Individually each of them work. When both of them are connected I get corrupted video as soon as I tune to another channel. There is no specific pattern in the logs, but now and then trouble about too large packets when communicating with the CAM appears in dmesg, which could make sense given the pervasive use of encryption by my cable provider. I have kept a log of most of the things I've already tried here: http://ubuntuforums.org/showthread.php?t=2054643 Is this a common problem when you use two of the same tuners? Who can help me fix this problem?
