Macrovision disable

The best card for running your DVD through a VCR (which is where Macrovision screws things up) is a DXR decoder card from Creative. You can also find macrovision fixes for nVidia at <A HREF="http://www.digital-digest.com/dvd/nvidia/index.html" target="_new">http://www.digital-digest.com/dvd/nvidia/index.html</A>, but the DXR works better, using software found at <A HREF="http://www.digital-digest.com/dvd/articles/macrovision_hardware.html" target="_new">http://www.digital-digest.com/dvd/articles/macrovision_hardware.html</A> to disable Macrovision.

What's the frequency, Kenneth?

BULLSHIT! Macrovision detects that it's connected to a RECORDABLE DEVICE and throws the picture into a tizzy! Your talking to experience here.

Heck, I tried connecting a VCR to my friends TV w/built in VCR, and even that went into copy protection mode , with no way to fix since the VCR was built into the TV!

What's the frequency, Kenneth?

crashman is definitely right... as soon as it detects a connection to the recordable device, it will either make the screen flicker black every so often, or from color to black and white, or just fade darker and then brighter again.. but he's definitely right.. even when i hook my dvd player up to my vcr (my tv is old as [-peep-] lol) its protection comes on

Actually, if it is anything like a consumer dvd player, macrovision is output all the time when the dvd movie tells the player to turn it on, not just when it is connected to a "recordable device". Whoever heard of a projector that could record? It is a combination of the macrovision signal and the gain controls in a vcr which cause the sync problems, ie brightness variation, colour switching and screen rolling etc.

And for the benefit of anyone that doubts my intentions here, I want to connect my card to the vcr in my daughters' bedroom and output the picture from the rf arial socket as they only have a 14" portable with no av socketry

Just when I thought I was out, they pulled me back in!

I know that at least the case of computers, they can detect whether Macrovision is used or not on the DVD. As for consumer DVD players, I think they probably do the same.

I know of quite a few ways to get around it.

No that's bull, macrovision is not "detecting" anything. Macrovision messes up the video signal is a why that TVs don't mind (mostly anyway), but will screw up the AGC in VHS VCRs. The macrovision signal is always there.

Macrovision is the standard copy protection method used on both vhs and dvd (analog) copying, CSS is the standard for dvd digital copying.

Some old vcr's, and indeed some current ones, are unaffected by macrovision because they have Auto Gain Control (AGC) set at a level so as to not be screwed up by the macrovision signal. Tv's do not have this circuitry, but projectors do. Even so, some tv's can be affected by the macrovision signal. Disney videos were notorious for having a high macrovision level, in Europe at least, and caused many tv's here in Europe to screw up. Macrovision is carried by both composite and S-Video connections, but not component output. That is why component output (RGB in the UK) is the video connection of choice for projector and HDTV users. But there are no consumer vcr's with either component or RGB inputs, therefore macrovision is a supposed safe format. There are macrovision disable boxes available that fit between either dvd or vcr to vcr, allowing successful taping. But doing it through software would be a far more economical exercise.

Incidentally, Laserdiscs were never macrovision encoded.

Macrovision IS present all the time when it is enabled, but it is just a signal and cannot detect what type of equipment is attached to what.

Here is an FAQ answer on Macrovision AGC and Colorstripe...
http://www.techtronics.com/uk/shop [...] ision.html

Macrovision has no effect on some non-vhs recorders, for example TiVO can record a macrovisioned signal, the macrovision is still present in the output.

Lots of info on the law requiring manufacturers to cripple their products to support macrovision can be found here...
