If you have a dvd recorder/vcr combo or if you have an old vcr hooked up to a dvd recorder, you should be able to record home movies to dvd. There shouldn't be any macrovision on those tapes. If for some reason, the recorder says that you cannot record due to copyright protection, there are devices available on the internet to bypass those. I bought one off ebay several years ago when I was making copies of my own tapes.
As for other tapes, copyright laws allow people to make personal copies of movies they already own for archiving. As long as a person is not selling or sharing the copies, there is nothing anyone can or will do.
