You may have to use modprobe.conf to force the right card to be
recognized. Something like:
options bttv card=10
*edit* NM I found your post on zoneminder forums, and your dmesg output
that you have there seems to indicate the card is detected properly.
Are all of your /dev/video* devices there?
I wonder why its using V4l2, I thought that was a v4l1 device. Hmm.
Sorry, I'm not much help at this point :)
