I recently installed teh 64 bit Archlinux on my amd64 desktop. Everything was working fine until recently and now I can't watch TV anymore. I use mplayer to watch TV. I simply run mplayer /dev/v4l/video0 and if I have to change channels I just use ivtv-tune --channel =<CHANNEL NUMBER>. Now When i run I see the following error and mplayer does not start. is this a ivtv problem or mplayer problem.

Also I think the ivtv module is working fine here is the output from dmesg

I also tried the cat command and view it with another program like vlc. But the video file seems corrupted.
cat /dev/v4/video0 > test.mpgThanks for you help.
