I want to copy from laser disc onto my PC, and then author a DVD from the captured video. That much is simple. What I also want, however, is to try and eliminate some of the NTSC artefacts in the source video (crosshatching, bleeding). After reading a bit, it sounds like a line doubler is what I want. Any suggestions on this? The line doublers I've looked at so far have component and/or VGA output. I'd need some way of capturing this (my current capture device only takes composite or S-video inputs).
