 United States fair use law, as interpreted in the decision over Betamax (Sony Corp. v. Universal City Studios), dictates that consumers are fully within their legal rights to copy videos they own.However, the legality has changed somewhat with the controversial Digital Millennium Copyright Act.After April 26, 2002, no VCR may be manufactured or imported without Automatic Gain Control circuitry (which renders VCRs vulnerable to Macrovision).
