Macrovision: The Copy Protection in VHS

Video Description

You can support this channel on Patreon! Link below Did you ever try to copy one VHS tape to another and find that it just, well, didn’t work? Macrovision was the clever creation of what is now TiVo that managed to confuse a VCR without causing too much distress to a TV. In this video, we find out what it is, how to spot it, and how it works (with a healthy dose of speculation).
