Capturing with Winfast VC100.

Hi.

I'm pretty new to capturing video etc with a TV/capture card, and I just wonder if it's a sign of overheating if I get "lag-lines" when the picture moves. I don't get any of those when I watch/record with a pixel height of 288 (ie, I can capture at 756*288 without any lag-lines). It has nothing to do with the codec, so I'm beginning to wonder if it's hardware related of software related.

For example, I was recording a clip off my xbox, playing halo, at 640*480, using Picvideo's MJPEG. Or well.. I've been recording like 20 clips, but to get to the point. The laglines aren't there all the time when I capture off Halo. Sometimes the frames are complete, perfect you might say, and when I tried facing a wall, just right up to the wall that is, and shot ~10 plasma shots, which causes alot brightness, the laglines reappeared. But then when I tried again to shoot into the wall again, the laglines disapeared. They reappeared each time there was a bright mesh or.. whatever on the screen.

When I record off a VHS, or off the TV at 640*480, the laglines appear just randomly. Except when I'm recording off the VHS. I tried recording some off a Star Wars vhs tape and the laglines were there all the time. When I recorded off Simpsons on the regular telly, the lines only came sometimes, when there was alot of movement involved.

Hope you can explain this for me.. Hmm, I'm expecting a very short answer like "dude, your card can't handle resos' that high, goddamnit!".

oh.. does this have something to do with interlacing? :P
