I disagree Sander. I've never seen a border that large on any capture,and all my captures are from the composite input on my PVR-150. Overscan would not cause that either. It looks like a sync issue, both horizontal and vertical, and I'm inclined to think it would be a single cause, tough I cannot think of what that might be without digging through the NTSC specifications. Scott, What resolution are you capturing at? What sources are you using? The captures I mentioned are from a small, digital satellite system and some reading implies the the digital source may not contain all the overscan than an analog broadcast could. I cannot easily change the source, since I have 25+ feet of cable and it's currently connected to the second output on the satellite receiver, and I cannot easily reach the other outputs. Can you try capturing from a few different sources? -Thomas _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
