Sod that, buy yourself a TV Out card... infact most cards nowadays have an S-Video Out.
What you do is setup your VCR and record some sessions to VHS/DVD/BluRay (which ever you have)
Then using a TV Tuner Import the Video and edit it up.
It saves getting an expensive card as TV Out cards are around $40 (thats if you don't just need an S-Video Lead) and a TV Tuner is around $60 for a decent one.
if you have 2 PCs and DVI on your Video Cards, there is software you can get which will take video input from that socket... as you can use your SVGA at the same time, this is a perfect solution for copying video in real-time.

Problem isn't actually Video Card speed, but actually Processor Speed when capturing video.
Also you'll want a nice fast HDD.
