Try stopping your backend and then re-run mythtv-setup. Delete your
capture devices and re-add them. That should take care of the problem.
(You will have to reassign the line-ups too)
As a test you should be able to manually capture from that device with a
command line similar to this:
$ cat /dev/video0 > ./test.mpg
^ctrl-C to exit and then you should be able to play it back with:
mplayer ./test.mpg
If that does not work then you need to troubleshoot why your ivtv module
is not working.
Good luck,
Bill
