/dev/video0 dissappeared!

Hi my pinnacle PCTV pro tv card has been working correctly on every suse including 9.1. But when I tried configuring lirc (remote control) using yast, tv card config it doesnt work any more. Only thing I did is that I enabled lirc, testing didnt work. The thing is, that now all tv applications show just blue screen, and don't show bttv option in device, instead they show just Nvidia etc. Also /dev/video0 doesnt exist any more. I tried unsetting tv card, resetting computer, again setting tv card but no results. Thanks.
