Copy protection??? |
|
|
I was trying to copy a golf tape for a friend. I have VCR 1 (playback)
connected to VCR 2 (record and monitor). The tape plays fine until I hit
the record button. Then the picture goes to crap. Is this how copy
protection works?

Basically, yes. Macrovision affects the operation of the AGC circuit
in the recording VCR. This circuit is activated when the "RECORD" button
is depressed. |

Clarification please?
The picture goes to pieces only when you start recording, or you see that the
recording isn't good when you play it back?
How does it look when it goes to crap? This will help to determine if it's
MacroVision or something else. - Reinhart |

The picture goes to pieces while watching DURING recording. What
happens is the picture gets darker, at times the screen goes to solid
blue (indicating no input to the VCR), then when the picture comes back
the colors are distorted and some tearing occurs. All of these
malfunctions are completely random. If I turn off recording, then the
picture returns to normal. The source tape is recorded at slow speed.

This sounds unusual - in all the vcrs i have worked on, the agc
circuit operates whether you press record or not - the E-E picture is
affected by macrovision material playing through the AV input,
irrespective of whether tape is recording or not. Maybe this is just a
European thing, or a quirk of design in the OP's situation??!

It depends on the design really, my JVC (as crappy as it is) does
exactly what the OP says his is doing. It lets you pass the signal just
fine when it's in stop mode, but as soon as you hit record the AGC kicks
in and you see the effects of Macrovision. |
