I will answer this and hopefully get some sleep (I'm in England and I haven't slept)
You can put any video material on your computer whether it's from a VHS or DVD player. With a VHS it will have to be (in most cases) done by anologue connection.
If your Video machine has a video output or a S-Video output you connect it (with a cable) from your machine to a 'Capture card' which you will have to buy from somewhere like dabs.com.
Software should come with it. I am embarking on doing this soon but what I do know is that one of the best capture cards and software bundles is Studio Deluxe V8. Buy it!
Please reply if you need to know anything else
