In the meantime, I tried mencoder on and on, no sound.
But it could be udev related ("udev issue" in link following):
http://linuxtv.org/pipermail/linux-dvb/2009-January/031362.html
as I do get with mencoder similar errors...

So I am also emerge'ing my Gentoo GNU Linux box, in hope that it'll
fix it itself...

OTOH, ffmpeg if I get it right, because I am getting much inferior
capture than with the ffmpeg line above... but if that could be fixed...
Thanx!
