Are you sure you have that round the right way? From the output below the Aver card looks like a straight bt878 framegrabber with no mpeg encoder on board. Therefore cat /dev/videoX >/tmp/test.mpeg will NOT work with the Aver card. I therefore think that video1 is probably the PVR-350 and video0 is the Aver. I am not 100% sure how to check, but there should be a log of kernel messages which will tell you. Also if you look at the output of lsmod it should show the (reverse) order of the modules loaded, the first one to load should be video0, the second video1 etc, although you can change this by passing options to the module (in bttv for the Aver the option is video_nr=X then the video device will be /dev/videoX) Try using a normal tv watching program like xawtv. It will work with a framegrabber like the Aver, but will not work with the PVR (as xawtv does not have an mpeg decoder). Try xawtv -c /dev/video0 and xawtv -c /dev/video1 The one that works is the Aver card. >Can anyone give me some guidance on how to > debug this?
