Wouldnt you know it - Ive been chasing this for days, and I stumble over
the cause a few minutes after sending the message :(

udev is numbering the video devices differently depending on the kernel
version.  As a short term fix, Ive just changed the capturecard to that
wanted by 2.6.19 - will have to look into a udev rule to to fix video0
to the wanted hardware.
