arma,
videodev is loaded by bttv, you don't need to modprobe it.
It already has major 81.
Do to see the major and minor numbers.
There is nothing wrong, your TV card should work

arma,
My lsmod shows | Code: | | videodev 10240 1 bttv |
which means that videodev is being used by bttv. I didin't do anything to load videodev. I added bttv to /etc/modules.autoload.d/kernel-2.6 and it just worked.
Do
