It is on the DVD's video output, composit, S, and component. Keep in mind it only affects VCR's, not TV's. If you are modulating the DVD output to an antenna system you will have problems with most TV/VCR combos or regular televisions when the customer uses the VCR tuner for channel selection. Some APEX DVD players can be modified for no macrovision, or use a copygard stabilizer to remove it before modulating.

Very odd fact: Beta VCRs never were affected by Macrovision, they process the video diferently than VHS does. If you run the video signal through an old Sony Betamax VCR it will remove the macrovision.
