Mencoder

[newbie at poq.co.za]

Hi There

I have a Brooktree chipped card. It's got 4 video inputs.
I'm trying to record video, no audio from all 4 channels
of the card using mencoder. I use fxtv to display video
on the seperate channels. I get video on all of them. This
is the command I use

fxtv -disableDirectV -inputFormat paln -deviceNumber 0
fxtv -disableDirectV -inputFormat paln -deviceNumber 1
fxtv -disableDirectV -inputFormat paln -deviceNumber 2
fxtv -disableDirectV -inputFormat paln -deviceNumber 3

So i got video on all of them, but when I record using
mencoder I only get video on the first device. Device
(1,2 and 3) got no video(blue screen). But from fxtv
it works fine.

mencoder -tv
device=/dev/bktr0,/dev/tuner0:driver=bsdbt848:width=640:height=480:norm=pal
tv:// -o tv.avi -ovc lavc -nosound
mencoder -tv
device=/dev/bktr1,/dev/tuner1:driver=bsdbt848:width=640:height=480:norm=pal
tv:// -o tv.avi -ovc lavc -nosound
mencoder -tv
device=/dev/bktr2,/dev/tuner2:driver=bsdbt848:width=640:height=480:norm=pal
tv:// -o tv.avi -ovc lavc -nosound
mencoder -tv
device=/dev/bktr3,/dev/tuner3:driver=bsdbt848:width=640:height=480:norm=pal
tv:// -o tv.avi -ovc lavc -nosound

I have read the man pages for mencoder, but still no joy.
Its probally a syntax problem. Can anyone please help me.

THANKS!!
