Cheapest/quickest way is to buy an HDD/DVD Recorder and plug in your VHS machine, then copy from VHS-to-DVD (or HDD)
I agree with the TV capture card route, however, some people don't have the full know-how or the right PC specs to do this.
Only works on home vids. If your trying to copy original movies then you need a channelizer - use to have one. They help with the signal and prevent that fading.
