s-video connection

[abrombo]

I am trying to use VLC to capture output from s-video. I am using a hauppage inpactvcb with one s-video and three composite inputs. The only video input on my computer is /dev/video0 (running ubuntu intrepid amd64, v4l2 is installed). The output from the verizon set-top-box is NTSC (tvtime and xawtv work when set to NTSC). When I try to use the video capture mode of VLC with all defaults except for setting NTSC I get a blue video window. If in the advance options under video capture I set the input to anything other than 0, I get no video window at all. Do you have any suggestions as to what I am doing wrong?

I also tested composite input. Both s-video and composite work with tvtime, xawtv, and cheese but not with vlc. Note that the version of vlc I used was obtained with 'sudo apt-get install vlc'.
