A gadget that goes between your two VCR's, or your DVD player and VCR, so you can copy videos and DVD's. They are also used so you can watch DVD's, period, on systems where you're forced to plug your DVD player into your VCR because your TV doesn't have a composite or S-video input.

Macrovision Buster in them. However, it becomes

pandering to the desires of the
movie industry.
Corporations have no
backbone.
