Thanks for the tip. I've tried all the other clients I could get my
hands on, including xawtv, mplayer, and xine. Unfortunately, I have
not managed to get a picture (or even an empty window) out of them.
Is there a way to get it working?
Mplayer plays local media files and DVDs happily, but when I
try to input from /dev/video, or use the tv:// args, it complains:
v4l2: ioctl dequeue buffer failed: Input/output error, idx = 0
over and over again. The other clients just hang or exit.
I'm not sure what to try next. Here is a typical log, I have tried
many variations, but the end result is always the same.
