Input/output error on /dev/video0 (PVR-350)
|
|
I can't get past this problem. I've built my mythtv TV machine several
times in the last 8 months (although I always seem to have something go
a little bit different) I've never had this problem. If I try to do a dd
or a cat of video0 such as below, I get an Input/output error. I've
tried what Jarod's guide suggests, rmmod and modprobe of ivtv, but it
still fails after I do that. In messages I get:
Apr 8 21:18:28 mythtv kernel: ivtv: Timeout waiting for data!
I've come up pretty empty on searches. Any suggestions?
Thanks,
James
