I have a video capture card in my computer.
Mine is a TV tuner card.
You need a fast computer, and a large fast hard drive.

For home movies that you want to keep,
I STRONGLY suggest you get this done professionally.
It's not as easy as hooking up a VCR to the computer
and just start recording. There are problems to overcome.
Dropped frames and out-of-sync audio are the two biggest.

And if you are copying VHS tapes to DVD don't expect DVD quality.
The quality is only as good as the input.
If you input VHS quality in, you get VHS quality out, or worse.

If you have a bunch of movies that you bought on VHS
before DVD became popular and you are thinking of transferring
these to DVD then forget it. Waste of time. Easier to just
get a subscription to NetFlix and rent the DVD and copy it.

Some people report great results with video capture devices.
For me it has been a mixed bag of results.

Hope this helps some.
