I never heard of that till now. The Macrovision signal, if present, is usually encoded onto commercial DVDs, not generated within the VCR itself. Your VCR must be an odd man out in this regard. Personally, I don't see the sense in generating the MV signal within the VCR and sending it over the RF modulator output. This would mean that all tapes played on that VCR, even home videos and other non-commercial tapes, would be MV protected by default, whether the user wanted this feature or not. I would think that any VCR having this particular feature would also have a defeat switch or some other means to disable it if the user decided he or she did not, for any reason, want to use it.
