As I wrote the patch solves the problem but now I have another one:)

I use the following command:
mencoder -tv on:driver=v4l:channel=e8:width=384:height=288:norm=PAL:chanlist=europe-west:adevice=/dev/dsp2 -oac pcm -ovc copy -endpos 00:01:00 -o test.avi

The problem is that the avi has twice the speed of the original TV program.
I tried with rc1 and the cvs version too and with -ovc lavc too.

The output:
