Post by Mark ZakI would like to backup two teaching copy protected NTSC VHS tapes to DVD.
The tapes are frequently used at various locations in class rooms often in
old equipment and I am concerned it is only a matter of time before damage.
I trust this is not illegal. I have Panasonic NV-FJ630 Series VCR and
Panasonic DMR-EH60 DVD Recorder.
Your advise would be appreciated

If they're not protected, you can simply run a patch cable from the
VCR to the recorder as you would for a VCR-to-VCR copy. There would
obviously be some degradation in the transfer, as it's basically a
digitized analog copy (yeah, sounds like an oxymoron, but it's not).
If they're commercially produced tapes though, they probably are
protected. Even tapes going back as far as the early 80s are
protected by Macrovision ACP (Analog Content Protection). You can
strip off most of the signal and boost the clarity using a "video
enhancer"/Macrovision remover device. However, that's where things
get hairy. Depending on the country you live in, using such a device
or even owning it can be illegal (you can thank the Americans for it
if your country adopted DMCA-like copyright amendments). It's kind of
a catch-22 situation. You can legally make the copy if you bought a
licensed copy. However, to make the copy you have to remove or defeat
the protection. Defeating or removing the protection is illegal. So
while it's legal to make the copy, you can't do it legally.
Further, such devices don't completely remove the signal. It just
tweaks the output enough that it doesn't screw up the picture. That's
fine for a totally analog copy like a VCR-to-VCR dub, but if you
digitize, some of the codecs used in computers and stand alone
recorders look for the non-visible signal cues, and will crap out if
it finds them. There are some capture cards that ignore the signal,
but I can't recommend one. I've no idea which of the current models
do or don't.
