[mythtv-users] /sbin/modprobe ivtv -- not working

[Ramon Roca]

Not sure, since you are using a newer version than mine, however, by the erors that you are reporting (look comments below)... are you sure that you have the devices defined?
try "ls /dev/diveo*", be sure that you have many video* there...
If not are there, try something like this:

 for i in 0 1 2 3 16 32 224 ;do if [ ! -f /dev/video$i ]; then echo "Creating /dev/video$i" && mknod /dev/video$i c 81 $i && chown :video /dev/video$i && chmod 660 /dev/video$i; else echo "/dev/video$i already exists";fi;done

Have luck,
Ramon

Everythinh was ok until here, and here, looks like is trying to register the video devices...
