[mythtv-users] mythfrontend not finding dev/video0..but cat does???

[Dan]

Ok doing a little more investigation...I found this in /var/log/messages at bootup

Mar 14 14:50:09 localhost kernel: ivtv: ivtv-api.c: unknown ioctl 0x803c7601
Mar 14 14:50:09 localhost modprobe: modprobe: Can't locate module char-major-81-1

Mar 14 14:50:31 localhost modprobe: modprobe: Can't locate module sound-service-1-0

could this be related....to the problem??

ok this is gettting frustrating..move past one problem..to hit another..

when attempting to goto tv in the mythfrontend I'm getting the following...

error reading from: /dev/video0
read: Input/output error
error reading from: /dev/video0
read: Input/output error
error reading from: /dev/video0
read: Input/output error
error reading from: /dev/video0
read: Input/output error

what I don't get is before launching the frontend, doing 
cat /dev/video0 > test.mpg 
works just fine....if I do it before launching the frontend..
I can't do the cat after the frontend attempts to use /dev/video0..

(of course this error is actaully produced by the backend....not the actual frontend)

thoughts??
