This is exactly what I thought too. However, $ ls -alh /dev/video? crw-rw---- 1 root video 81, 0 Jun 13 15:05 /dev/video0 crw-rw---- 1 root video 81, 2 Jun 13 15:05 /dev/video1 $ cat /etc/group |grep video video:x:27:root,roger,mythtv Executing mythtv-setup as root has no effect here -- after stopping the backend (with the conflicting EIT scan). I still get the multiple "Card 3 (type Could not open '/dev/video1' to ) is set to start on channel Please add, which does not exist." errors on mythtv-setup exit. Guess this guy's theory isn't correct. :-/ -- Roger http://rogerx.freeshell.org _______________________________________________ pvrusb2 mailing list [email protected] http://www.isely.net/cgi-bin/mailman/listinfo/pvrusb2
