Avermedia TV/FM card for video capture from a camcorder

I have an Avermedia TV/FM 98 card and I can watch TV on the PC. However
when I try to use that card to capture Video it does not seem to
work. I see that the drivers are installed correctly.

What I am trying to do is that I am connecting the S-Video output
of my camcorder to the S-Video input on the Avermedia TV/FM 98 card.
Then on the player when I select S-Video I dont see anything on
the screen

I also tried connecting the composite video output of my Camcorder
to the Composite input of the TV/FM card and it still does not work.

Any clues ?

Thanks,
