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.
