How to detect Macrovision?

[mouquai]

Hello,

how is it possible to detect whether my DVDPlayer has a Macrovision copy protection. I am not in a position to have a look inside the software. Is there a special media available or do i need special hardware to test it. Money is no problem :-)

Thanks

It is your DVD which will have Macrovision protection and not your DVD Player.

When you decrypt your DVD using DVD Decrypter, the log window will indicate if the DVD has Macrovision protection (as below):

easy way to find out - run it through composite into a VCR and try to record :)

unshinnyboy, I see in the log screenshot where it shows "Remove Macrovision Protection: Yes" - does that indicate definitively that there is Macrovision protection, or only that the box is checked? Furthermore, are there known negative effects from having it enabled if the disk has no Macrovision protection?

@CWR03, hmm..good question. I am not sure, so I will test it tonight and tell you (or you can test it yourself by having the option checked and then decrypting a DVD which doesn't have Macrovision protection and see what the log says). But I do have it always checked, and I haven't experienced anything negative with non-Macrovision DVDs.

DVDD defeats macrovision by default, if it finds none it won't affect the decrypt process, it simply moves on.

Do I read this right: the question is wheter the dvd player has macrovision protection enabled, not if the disc itself has it.

Normally the player would have it, to comply to the dvd specs. On many players you can disable it by the remote. you can check www.videohelp.com for that.

And the best way to test it is as described by mug funky.

OK, so that is another thing I learned - Players have macrovision enabled.

there is no macrovision program on a DVD....just a bit that is set on it to tell the DVD Player to output the analog protection bit to your VCR, which then messes up the recording. There is no issues with removing the bit from the DVD...doesn't wreck anything. There is a version of IFOEdit around that lets you add the bit to your DVDs that you burn....what fun....works too

Right.

I want to check if the DVD SW is in a position to note that feature.

i do not think any dvd software on your computer will tell you if macrovision is on...only way to tell is with vcr.

However, IFOEdit will tell you...I forget where, but it will have APS ON somewhere in it when you open the IFO

Like the above reply, I do not believe any of the popular software programs actually tell us if Macrovision was found on the disc. Even in their logs.

The only way I know of to test this issue is to TRY and make an analog backup, and then test the results.

And, while we are on the subject, I recall hearing awhile back that NONE of the Superbit titles had used Macrovision in any way... I have not tested this, but a friend confirmed it for me on one of those titles, when he backed up his "Das Boot" Superbit version to a VHS tape.

VOB EDIT tells you in the Navigation header whether Macrovision is set or not - 0000 for no protection and then multiples of 1024 (I think) for Type-1, 2 or 3 protection.

I'm guessing there's no Macrovision on Superbit for a couple of reasons:

1 - You have to pay for it, which studios maybe loathed to do on such 'niche' titles.
2 - It can have an adverse effect on projectors, which probably covers a large proportion of the 'superbit' market?

Ok lets describe my situatuation to get a background.

I have a audio/video player in front of me, which is bulid for automotive area. I want to check and test now wheather the third party software take notice of the macrovision signals on the media and add some macrovisionstuff. Video otput is RGB.
