Having a hard time setting this up. I go to video setting and adjust it to 640x480. I select my interface get the video in (ATI600). The picture of the video shows up but so do extra blue lines outside of it. I try to adjust the red lines but if I move the height then the width increases too. That cuts out part of the video. I've selected video capture device but it's acting like it's doing a screen capture as it records what's outside the actual vhs video. I really can't get a grip on how that red square works? Thanks for any suggestions.
