I've seen a similar thing with other models of bttv cards.
After mucking with the connection with system up and
seeing a blue screen, when I got the signal reconnected the
picture was black and white through the s-video connector.
This happened twice and each time it was fixed by powering
down the machine. Reloading the drive or rebooting didn't
help, I had to power off and drain the electrons.
