I have an older A/V unit which I have plugged into the line in. So, I can plug in any device to the A/V (Cassette player, turntable, VCR) and record to software (mine is Soundstage Mastering Studio). A VCR makes a great audio tape recorder, by-the-way.
There are a number of devices like turntables and cassette players that are USB connectible.
If you have in mind to rip movies from a VCR, you will need to find a way to connect the video stream and you will run into Macrovision copyright issues with most commercial tapes.
