Yes, this was the problem. Now it works.

One more question, if I may

When capturing, the audio is really bad in quality: it has an ugly echo. I
used this command

mencoder -oac mp3lame -lameopts cbr:br=224 -ovc lavc -lavcopts
vcodec=mpeg4:vhq=3:vbitrate=1200 -tv driver=v4l2:width=382:height=288
-o test.avi tv://

with Line input volume set to 1.

I tried many settings, both for the audio bitrate and the line volume. The
bitrate doesn't seem to play a major role, while the volume does: the
bigger the worse. But I can't set it lower than 1....

Any suggestion?

Thanks a lot
