Are you saying that the damage to the signal is generated by the video
tape player then? I have some difficulty believing this - isn't it
inherently in the data on the tape? I was able to copy video cleanly
from a VHS deck to a Hi8 deck BTW (expensive bugger that was -
Y200,000), but not the same material from the same VHS deck to another
VHS machine. I still think - from what I previously read (years ago, I
don't have the reference now) and also experienced, that the MacroVision
damage is within the data on the tape and not (actively) generated by
the hardware. Incidentally, the corrective circuitry I mentioned had
nothing to do with MacroMedia, but is part of the standard parameter of
television signal processing.
But never mind video! Actually, what I want to do is to record clean
audio! I don't care about movies! I don't *want* to copy them! I do
want to eventually digitize my own Hi8 tapes, but that's a different
story again. Any info on audio?
