Hi all. I have a piece of video I'm capturing from VHS for conversion to VCD, but there is a defect in the video that is absolutely killing my MPEG encode quality. There are 3 horizontal lines of distortion that slowly scroll upward through the picture for the duration of the show. It appears to have been a defect in the cable transmission, like some sort of electrical interference (the cable system I recorded it from at the time was pretty shoddy, as I recall).

I have managed to minimize it where the defect isn't really that noticeable using a variety of VDub noise reduction filters, but the problem is that the distorted areas seem to be sucking up all my MPEG bits, causing the rest of the picture to show blocks and other MPEG defects very badly. The finished video looks absolutely like sh*t, although I have made lots of almost perfect quality MPEGs from VHS caps of similar quality before.

So far I've tried flaxen VHS, dynamic noise reduction, and smart smoother high quality with mixed success. Does anybody have any suggestions for how to remove these lines from my picture, at least how to get around them for MPEG encoding purposes?
