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...
