It's not the FAQ issue, I'll try to clarify. The sound in mythtv just sounds
bad. It's not an echo like if there were two feeds going. There just doesn't
seem to be much range and quality to the audio. It's as if it were an mp3
encoded with a really low bit rate, if I were to try and describe it as
something you may have heard. If I just unmute the line-in and hear the
direct audio it sounds good though. So I know it's not the audio feed, just
something going on when it is recorded.

That's what I was afraid of hearing :( It sounds good when it is not muted
though, it can't be the leadtek...? The leadtek seems to be sending a good
signal.
