I have an AverTV Stereo card (BT878), which works pretty well, but has weird tuning problems. about 80% of channels come in fine. The other 20% have perfect video, but no audio. Tuning with xawtv, I can sometimes get the audio to come in, but the picture will be completely garbled, and in some cases, I can't get the audio no matter how much tuning I do. using us-cable-hrc (instead of us-cable) will get more of the channels audio, but again, most of the video is incorrectly tuned, and tweaking the tuning in xawtv doesn't seem to help. I have tried using auto, mono, lang1, and lang2 audio channels, but this has not helped. In windows, everything work perfectly, and it generates a binary freq.tbl file which I assume has the channel tuning info in it, but I dn't know how to read this file. I am using card=13 and tuner=2 I use the loopback audio-cable, as I don't think this card has a usable audio decoder (at least tvaudio can't find one) As I said, it is pretty weird, because the no-audio condition only seems to happen on random stations. they aren't grouped together or anything. Any ideas on what I can do?
