Asus TV-FM 7135

Hi everyone
I have SUSE 11, my TV Card dosent work correctly, I am using Kdetv/Kde3 all the time I open the program appears a message saying

Unable to grab video.
Video display is not possible with the current plugin configuration. Try playing with the configuration options of the V4L2 plugin.

I configured it and i could scan the channels but nothing appear I mean I cannot see any video and the same message appeared again.

what I should do to resolve it

Thanks
