*UPDATE*

Any of "pcm" or "mp3lame" as audio codec yields an mpeg file without any
audio.

This is de command line:

mencoder -ofps 25 tv:// -tv
"driver=v4l2:device=/dev/video0:width=352:height=288:fps=25:forceaudio=1
:audiorate=32000:amode=1:forcechan=2:adevice=/dev/dsp"
-oac pcm -of mpeg -ovc lavc -lavcopts "vcodec=mpeg1video"
-o test.mpg
