[mythtv-users] Can't capture using PVR250

[Shawn Flynn]

Hello All,

I have been trying to install a PVR-250 (Freestyle) card in my Myth box, and
appear to have hit a problem that I just haven't been able to figure out. I
have been following the instructions in Jarod's excellent Fedora HowTo and
everything appears to install correctly, but I cannot seem to get anything
out of a 'cat /dev/video0 > /tmp/test_capture.mpg' It always returns after a
few seconds with an error 'cat: /dev/video0: Input/output error' and a zero
length .mpg file. rmmod'ing the ivtv driver and re-loading it doesn't appear
to make any difference. I still get the same error.

Below I've appended the output from whatever I thought might be pertinent. I
don't see anything wrong in it (not that I really know what I'm looking for)
but was hoping someone on the mailing list could have a look and maybe see
something that I've overlooked. Any suggestions as to how to troubleshoot
this would be most welcome.
