you will need a video card that has a "video in" slot on it so you can hook up your vcr. Then you will need to capture the whole movie onto your hard drive with a software which will be usually provided with the card.

You will then need to convert the .mpg file to dvd format and burn the files onto a dvd using a dvd burner

long method but less expensive as compared to some of the stuff used by studio guys to convert vhs to dvd
