I'm guessing you're running devfs? Thus every node in the world.
If not, and you really are running udev, then edit /etc/conf.d/rc and
change - RC_DEVICE_TARBALL="yes" to "no" and reboot. That should
clear out all the useless nodes.
Have you tried /dev/video1?
Also, do all nodes exists in /dev/v4l? If I were running MythTV,
I'd have select one of the modes from -
chi rsanders # ls -l /dev/v4l

According to xawdecode -h,
-c video device
video4linux video device. For devfs enabled systems, default is
/dev/v4l/video or /dev/v4l/video0, in that order. For non devfs
systems, default is /dev/video or /dev/video/video0 or
/dev/video0, in that order. Note that on /proc enabled systems,
video device detection is automagic.
