How to set s-video input for video capture

[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 and S-video). 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? Note that I can use VLC to capture video from my webcam using v4l2 (I have downloaded, compiled, and installed the latest v4l2 package). I would think the video channel would be 2 since for tvtime and xawtv the S-video input is always the third menu option (for my card the first input is Composite0 and the second Composite1). I think I am not setting the video input for S-video correctly, but I do not see what I am doing wrong.

Additional information. I tried using the composite inputs of the video card and one of them worked. The problem is definitely setting the correct input of the video capture board.

I have solved my problem. On the command line 'vlc --v4l2-input 2' works to set the s-video input on the video capture board input, but using the gui control panel under 'media->open caputure device->advanced options' to set input does not (in fact I am not sure anything in that control panel works or I don't know the correct way to use it).
