I use a few tools to do this. First off, the PC must be pretty fast (I'll write over 1GHZ) to use a card from http://www.hauppauge.com as a video capture card. For slower machines, the Dazzle 150 or better from http://www.dazzle.com will do nicely.
As to making the final DVD, your DVD recorder should have a bundle of software for the final work. Be aware that patience is needed since a hour long video will take 1 hour to capture, some time to edit and some amount of time depending on the PC to prepare to record the DVD and then (finally) some minutes to record the DVD.
I'm looking to connect my vhs-c camcorder to my dell pc, to burn tapes to DVD. Is there an adapter of some sort to connect RCA jacks to a modern pc?
