It doesn't sound like your /dev/video* devices are set up. You can check: ls -l /dev/video0 Mine looks like: mythos:~# ls -l /dev/video0 crw-rw---- 1 root video 81, 0 Mar 13 15:38 /dev/video0 After a quick search, I couldn't find the corresponding bit of the official docs, but thsi is from my personal install notes: ---- Run 'source /usr/src/linux-2.4.22/Documentation/video4linux/bttv/MAKEDEV' or similar to get the /dev/video* devices set up. The ivtv install supposedly takes care of this, but no dice for me. ---- And then there's this thread I found in Gossamer: http://gossamer-threads.com/lists/mythtv/users/22231 You may have to adjust some of the details to your specific setup. Good luck. -- Mark Matula Mikey, you will be missed: http://eblo.ratula.net/mikey.html
