It could make quite a big difference, raw cap from an X9 vs mpeg2 encode from V8, especially if the X9 don't have the color smear the V8 had.
I have said it before and I will say it again, I think you would get really nice results with your great AfterEffects skills if someone capped relevant parts from the old pan & scan LD's, the '85 standard play comes to mind. But then the capture needs to be a really good one of course.
