If you can't play a previously working tape on another TV, then you probably clogged the heads and the timing is incidental. (or the VCR just broke on it's own) The AGC in on the input only, not the output. (and it's actually taking advantage of poorly designed VHS electronics - Beta rarely had any problem with Macrovision due to it's superior video processing circuits)
While Macrovision has been seen on HBO and other analog premium channels, digital usually uses flags that newer VCRs (post year 2000) and recording devices detect and just stop recording. Since they have to pay for each use of Macrovision (licensed), it's use is not that common (as I understand it - no personal experience since my recorders don't recognise either protection method)
