It can't open the device. You probably aren't in the right group for access. I suspect it'd be the video group, just do: ls -lhd /dev/video0 ...and see what the permissions are, it's probably going to be root:video. For my mythtv card, I know for sure it's root:video. If that's all it is, use gpasswd and add yourself to the group then log out and in again. Dan
