Usually, you would buy a VHS to PC converter and software that would come with it to transfer your VHS to your computer for DVD burning. Check out http://www.dvdrhelp.com for more information on where to get the hardware and software.
I think i would hook up the vcr to my tv input on my video caputer card, and then record all of the videos, render them, and then put them on a dvd. A round about way of doing it, but that is what i personally would do. However most likely not the best way.
or you can visit and try VHS to DVD and transfer your home video tapes to dvd. You can get a pretty good conversion at a reasonable price from a lot of places. But what are most of these companies lacking? Care and attention to detail! Other ways you get totally amateurish product done with domestic equipment.
