HELP! Macrovision & VCR
Israel Colon
I would like to make back up copies of commercially produced video
cassettes. I know some VCRs are not affected by macrovision. Does
anyone know any CURRENT VCR make and model numbers which are immune to
macrovision.
Thanks in advance.

Just buy a 'video stabilizer'. It will remove the macrovision.
I've seen two different brands available. One costs $20 and
the other $30. I've seen them in mailorder catalogs such Damark
and Heartland America.

Beta and 8mm VCRs are immune. Go Video double VCRs are immune. Your 8mm
camcoder is immune. Copying from Macrovision to 8mm or Beta and back again
to VHS will preserve the Macrovision problem. But with a Go Video copy,
it's really gone.

The only ones I know off are the dual-deck models made by Go Video.
Otherwise, you'll have to buy an older model VCR that was made in the
pre-Macrovision days.

This won't work. You will just get a Beta or video 8 copy that is still
Macrovision encoded. The only way to remove it is with one of those
black boxes.

macrovision really has nothing to do with the age of the VCR.. they all
still have fast AGC's in them.. i have a really old Phillips HiFi WAY
pre-macrovision and it is still affected badly by macrovision.. in fact
prolly more so than the newer recorders.

comment but for PAL which is available in Australia and other countries
the Video Stabliszer RX11 doesn't work at all. You cannot even make the
timing adjustments necessary through different capaciors etc. Here is an
excerpt from someone who knows the details.
"I was able to establish what needed doing to help it work with PAL.
This consisted of:
1. Disabling the "type A" blanking, because that is only ever going to
work
with NTSC as far as I can tell, and there is a link provided for the
purpose.
2. Setting another link to eliminate 16 lines following the V Sync pulse
(option:- 11 or 16 lines).
3. Adjusting the line blanking period to 60uS to suit PAL.
4. Lifting a small capacitor to improve the sync circuitry a little bit.
The unit works to an extent, but because of the design of the sync
seperating circuitry it is very sensitive to any noise from the VCR (and
the
Macrovision signal it is supposed to remove!) and this causes
intermittent
spasms in the V sync which affect the record VCR.
There is little likelihood of improving it. It is a clumsy design with
lots
of basic weaknesses and it was really only designed for NTSC. I doubt
that
it works much better with NTSC, guess that's why they're cheap.
The EA unit would have to be 100 times better. Keep in mind though, that
all
the timing errors inherent in tape playback are still passed on to the
recorder and then compounded by it's timing errors. The only 100%
effective
way to produce a clean, stable tape copy is to use a Timebase Corrector
(TBC)."
The EA unit being refered to is a project availble in Australia through
JAYCAR electronics.

That's interesting! I have an older Panasonic hi-fi VCR that I use to
record movies from a new Sharp hi-fi VCR and it copies just fine with
no problems. If I record on the Sharp though, the Macrovision kicks in
and screws up the video. I guess I'm lucky then!

Matsushita made VCRs from 1987-1993 or so are completely immune to
macrovision. Also, most Beta VCRs are immune as well as a few older VHS
vcrs from various companies. I think it is now part of the VHS standard
that all VCRs must respond to macrovision.

8mm vcr's also ignore macrovision. My Sony EV-C3 happily copies
macrovision encoded tapes and I must say the quality of the copy is
outstanding.
