OTAHD: Thank you. Over time, there have been various versions of Macrovision. The system that was used in the days of VHS is different then the system that they are using now. Go to: www.liksang.com
This company sold tons of Macrovision Busters over the years. Now it appears that Sony was finally successful at putting them out of business. Sony sued them into oblivion! Of course, there are numerous companies that pop up all the time to take their place such as www.macrovisionbuster.com
These companies are a dime a dozen. Aversge price sseeme to be about $35.00 Frankly, there aren't many movies that I would want to see more then once anyway.
