Vidcap problems (v1.12)

Hi@all
I've installed R4 1.12 to test the vidcap feauture using my ATI graphics card (ATI 9600). So I realized that vidcap isn't working with the video-in of my ATI card.
Then I used a simple TV Capture Card (PCI, Philipps Tuner). It worked, but the resolution of the video-in is very bad (320x240). The card is able to view the video-in using a resolution of 720x576. Is there a config file in which I can set the resolution R4 will use for the video input?
