vcr's. I know how to record two tapes, I have no problem with home made
tapes recording VCR to VCE. The problem is with recording rental tapes VCR
to VCR. Are these rental tapes protected in some way and are there any work
arounds. The recording comes out but it is distorted.

There are devices out there which will remove those `copyguards' from
rental tapes. Check out the back pages of Popular Science or something.
Does anyone know how the copyguard works?
thanks

Are all rental tapes copyguarded i.e., Blockbuster?

Yo,
This copyguard or rather Macrovision's copyguard works on the prinicple of
playing around with the black level reference of the composite video system.
After modifying this level, most TV can still see, but some TV may not
work. As for VCR, it needs this level to control their internal AGC. This
copyguard thing will trick the AGC and thus record a distorted picture.
U can either use the copyguard eliminator(so called) or u can turn off
the VCR's AGC by modification. Of course in my case, I own professional VCRs
which have more advanced features like manual AGC and TBC system to totally
render all this "copyguard" useless.
Cheers,
Paul

Since it's against the law to record rented tapes, I wouldn't be
advertising that you are thinking of doing that, if I were you.

It would be appreciated if you read the title of this newsgroup! The word
"publish" is right there in it. This is not comp.electronic, it is
comp.publish.electronic -- meaning, this group deals with electronic
publishing, NOT electronics assembly or parts or using electronic
devices...

will assume that this is your intention. All that they do to make rental
takes, and many purchased tapes for that matter, uncopiable, is mess with
the time code. To low grade consumer decks, this has little interference
when playing, however, it willnot allow a second VCR to sync with the
first in order to tape. To bypass this, simply buy a time base corrector.
You can get cheesy low end versions out of the back of magazines for $50.
Or you could get a $20,000 Sony unit. My reccommendation is to get a good
mid range. Videonics has the best pro-sumer units that I have seen, and I
believe that they have recently come out with a stand alone TBC only
unit. I don't have there number handy, but if you call any respectable
mail order house, they carry Vidionics. Another piece of advice, stay
away from Sima, their stuff is crap, first rate!

You need either a Macrovision eliminator or else you need to have an
OLD VCR with doodley for an AGC to do the same thing for you!! The
Macrovision protection takes the form of some doodle on the blanking
pulse that makes the AGC think that bright will be TOO bright, and it
dims it out, or else you need to disable the AGC (Automatic Gain
Control) in your VCR and adjust the average by hand, (often not even
necessary!). Mine will record ANYTHING. Old RCA (Hitachi's) are known
for this deficiency/feature!! ;->

If you look in video magazines, you will see ads for units which
eliminate the "jamming" signal sent out from the tape running in one
VCR to the other "receiving" VCR. Those units do work...
Good luck!

that tape encoded it with MacroVision, what the quality will be.
MacroVision is a copy protection that makes copies distored, with color
flashing, light to dark contrast. Not all commercial tapes are encoded
with MV and devices used to be on the market to override it. I believe
that they are no longer available. To copy a commercial tape for your own
use is legal, but if you show it to a group, try to rerent it you can be
in for a very large fine and a jail term. With most movies being released
at a sale priced amount, if not when first released, but 6 months later
they ususally are, why go to the trouble??? If you can't wait 6 mo. most
video stores will sell used copies after 6 weeks of release for under $10
(ask you local video dealer to hold one for you). Hope this answers you
question.

in the vertical blanking interval that change in intensity and go brighter
than bright white. This fools the automatic gain control on the recording
vcr. You can get a device to stabilize the picture by stripping the junk
from the vbi for $30 to $60. Macrovision causes problems with some older
televisions. Don't use the device to violate copyright laws as that would
be wrong.

I don't think you're supposed to be able to record from these tapes. It
sounds illegal to me!

Please cite the source of your info that copying a commercial tape for
your own use is legal, unless you BUY a copy of the tape first and are
only making ONE backup copy for archival purposes. I don't believe
copying a copyrighted tape you've RENTED could be legal for ANY purpose.
I'm not equating theory with reality here, just wondering if you really
understand the laws in the USA.

multi-post. Many of these groups aren't interested in the video tape
duplication, or are not even remotely related to it.
Here's a quote from the Electronics Groups FAQ:
Q. "I heard in a back alley that crossposting was, you know, bad.
So should I post, uh, seperatly to each of the 14 newsgroups
that look sort of like what my question, you know, fits?"
A. The only thing worse than crossposting a dozen newsgroups is
multiposting the same thing to each of that many groups.
Try to limit the posting to the one newsgroup whose topic
matches your subject. (A lot of us read many of these groups,
and about the third time a subject comes up, so does the
irritation level.) ...
If it does seem to overlap a couple of newsgroups' topics,
crosspost instead of multiposting. Any competent newsreader
software will only show the the crossposted message to the
reader once. (Yes, there is a lot of incompetent software
out there.)

I have heard that copying between two VCRs is possible,
even if the tape being copied is 'copy protected'
I was told there was an extra 'signal' of a certain freequency(ies)
recorded alongside the audio/video signals on the original
tape, which does not affect the video display/audio output,
as its frequncy does not lie within those used for playing
a tape (maybe higher than the audio spectrum and lower than
the video spectrum(?)), but when this combined video/audio/extra
signal is applied to a recording circuit, the extra signal
interferes with the IF/modulation/bias (?) circuitry causing
resonance or something .. er.. guesswork time now :)
Apparently the solution to this is by means of a simple filter,
but without knowing what this signal is exactly, it cannot be
filtered out :o)
Performing this would be illegal, but its very
interesting to know what are the methods of making a copy
protection system for devices (VCRs in this case) which
are not designed to have any such system in their original
hardware specification.
Any real techies able to tell us more?
cheeeeeeeers, pi.

AFAIK, in all of civilized world, one can make ANY number of backup copies.
When backing videos up, I would pass the signal through a time-base corrector,
if I could get a hold of one.
The matter of rental tapes holds.

modification of the black level of the composite video system. Normally
it is used for referencing purposes. During playback, the VCR do not
need this signal at all. Sad to say, but some TV do use it, and thus it
may even cause the ORGINAL tape unwatchable on some TV.
On Consumer VCR, this reference level is used to control the AGC of
the video section during recording.Since this signal have been modified to
render it useless, the recording system "breaks down" and record a distorted
signal.
So, the method is not that of just removing a signal, as the black
level is embeded right INSIDE the video signal. Bypassing can be done not
only by using special circuit, but can also be achieved by removing the
AGC system of the VCR. Either that or if u would like, get a professional
VCR which have manual AGC system. More high-end model have a TBC that
TOTALLY remove this protection. And on top of that, a TBC helps to
make better copies, esp if u are talking about multi-generation copies.
With this, I am by NO means trying to teach u(the reader) how to
copy a tape that u have no copyright to it. Whether it is right or
wrong to do so, u decide for your own.
Cheers,
Paul

It's NOT illegal to teach people how to circumvent the law or break
the law. It's only illegal to break it yourself and get caught doing
it and be proven guilty! That's the way they wrote the fucking law! If
they had really believed that morons would come turn themselves in,
they'd have made THAT a requirement of law!! It's not even illegal to
recommend to people as an opinion that its a good thing to break the
law! It's not illegal to publish whole BOOKS on how to break the law!
Some morons will grind their teeth about it, but there are morons to
grind their teeth about pretty near everything that's fun, so fuck 'em!

Well, yes, this is prohibited, BUT, the movie usually comes out in
weeks or at the same time on Pay-Per-View, and you have the right to
copy it then, and my cable company TOLD me that. They get that right
with the presentation rights. We DO have the right to tape off TV now
not for public or charge displays. The cost is payed in a corporate
tax on the manufacture of tape. The Congress took care of that for
audio and video display. The only prohibitions are multiple copies of
copies of CD-ROM to DAT over and over with the copy bit disabled, and
the rental movies with the FBI warning, and any other agency which
asserts a time limit on retaining use for group showing. But your
right to keep TV presentations is law now. So just DON'T COPY the
FUCKING FBI NOTICE, silly!! ;-> Most people should have enough sense
to remove all that artifact!! There may be more in the teletext lines,
but have you heard of the "tape police" or the "disk box police"? I
haven't for private consumers. Go rag someone else about a matter of
REAL law, not TOY law!!
