Had a 1700+ Athlon and Nforce2 Mobo. Now a 146 Opteron and an Nforce3 board and this command that was recording audio is not.
mencoder tv:// -tv driver=v4l2:input=1:width=384:height=288 -oac copy -ovc lavc -lavcopts vcodec=mjpeg:vbitrate=2000 -o Harry3.avi
I know with Ktv the audio in is now AUX instead what it was which was LINE IN. I don't use the card to capture audio, but just a regular input port on the sound card [onboard]
