I can record movies from TV using V4L and Gnome2. I run the next example 
command:

jlopez at linux:~> mencoder -tv driver=v4l:width=768:height=576     -ovc 
lavc -lavcopts vcodec=mpeg4:vbitrate=900     -oac mp3lame  -vf 
crop=720:544:24:16,pp=lb -o output.avi tv://


And obtain the next output:

The output doesn't match any error, but the movie has no audio playing 
it with MPlayer or avifile.

Using 'transcode' I have the same problem: the program can open 
/dev/video0 and /dev/dsp0, but the movie has no audio.

I need some help or comment. I run Suse Linux 8.2, kernel 2.4.20 and a 
Creative sound card. Running Gnome2 and the following programs...
