Amazon.com: Camera & Photo: Sima CT-2 Video Signal Processor
This is a curious sort of device. When one reads the marketing description it's hard to see what it's good for. On reviewing the user commetns the value is rather more obvious -- it defeats Macrovision protection. So you can, if you're an honest sort, copy your old VHS video tapes to DVD. Or, if you're dishonest, you can make copies of rental DVDs and videos.
... what yu really need is a unit which will fully override both types of Macrovision, and to my knowledge, the only thing available is the SIMA SCC-2 Color Corrector 2. This thing is expensive ($150-200 bucks), but it's worth it if you have a big video collection you'd like to transfer to DVD-R. I hope this helps anyone out there who bought a bunch of VHS tapes and simply wants to transfer a few to DVD. Jeez....
It must be interesting to market a product who's primary value can never be described! The device does not seem terribly high quality. Some reviewers indicate they had to transfer the audio on a separate cable.
