I just tried a SoundBlaster Live 5.1 bulk (emu10k1) instead of the
onboard ALi card (intel8x0), but I get the same problem. I also have
some other old cards in my junk box (ens1371, sb16, crystal-???), but I
don't expect them to do any better.

Here is an excerpt of mencoder's output:

The messages come in chunks ca. every 0.5 seconds. I have a feeling that
mencoder changes the way it fetches video frames from the v4l driver
when I use forceaudio. Could this be possible?

Ciao
