Not sure why you are looking for tapes without Macrovision. It is very very easy to copy tapes with it.

My current setup can do it, and I imagine most other people around here could do the same. Especially if you have a capture card of some type installed on your computer or something like an Canopus ADVC110.

Macrovision essentially used trickery to make older recorders THINK there was a problem with the signal, thus you would just get a bunch of tearing and chroma goofyness. Any modern recording method (like the ones I mentioned above) pretty much just ignore the trickery from Macrovision.
