Macrovision

Has anyone ever added macrovision and encrypting to an authored DVD?

I have a client with original video to author and copy protection is required.....
I use Spruce up or Maestro.

It is capable of using encryption. However, if I'm not mistaken, you have to pay a licensing fee or something like that to obtain an encryption key from Macrovision. You might get more information if you were to contact them directly.

Not only do you need to obtain a license, you must submit the DVD to a "pressing" facility (usually via DLT), since DVD-Rs do not have (actually, CANNOT have) the capability to store the CSS key. As for Macrovision, I imagine that you have to obtain a license from them, also (Macrovision can be put on a DVD-R). This client sounds like a real pain-in-the ass to deal with. I hope that you have charged them accordingly.

Either of your authoring packages is capable of DLT export. For Spruceup, both Macrovision and encryption will have to be added "post authoring" of the disk. Like I said, this disk has to be manufactured... it can't be burned.

uhh, DVD-R(G) cant have CSS/Macrovision info, DVD-R(A) does.

I always thought Macrovision is added to video-files. So how else would it work on VHS-Tapes?

Neither DVD-R(General) nor DVD-R(Authoring) can have a CSS key installed (burned) on (in?) them. The area reserved for this info in the lead-in area is PERMANENTLY EMBOSSED / OBSCURED by spec definition (and yes, on BOTH of these versions).

Macrovision is simply something added to the Vertical Sync pulse, which can easily be done with either DVD-R version.

Mosaic, I understand your client's wishes, but if I were you I'd save yourself, and your client, a lot of wasted time and money. Both Macrovision and CSS are **EASILY** defeatable these days, so although this is something copyright-watchers are loathe to admit, it's a simple matter of fact. Why spend thousands of dollars/pounds on CSS or Macrovision encryption when anyone can download FREE ripping software to defeat it in a matter of seconds? It just does not make economic sense to pursue, and employ, largely-redundant technologies.

Provided that you are careful, and polite, in your explanation to your client, I cannot see why they would continue to pursue the issue - it's not a reflection on you, as an authorer, it's simply the current status quo in the industry.


Arky ;o)

I've put a lot of thought into this issue and here's what I think:

Macrovision is still useful. I always had trouble with making copies until I discovered the solution that you all are aware of (if you aren't, don't ask me). It's expensive though, the producer of the content must have a license with Macrovision.

CSS is still good in a certain way. I as an author would like to copy whole video_ts folders from a DVD to my HD in order to run various emulators and debuggers to learn how the 'pros' do things.

But I agree that the benefit of both is pretty small these days and certainly not worth the cost.

Personally I would try anything to persuade a client *not* to use Macrovision! I've always considered it a stupid waste of time and money, and as Arky says it is easily bypassed by anyone serious about making a copy or whatever.

If your client is worried about having his content stolen, maybe a good alternative would be to place a logo or "bug" in the lower right corner of the frame?

Just my $0.02.

I once heard rumours that already a very old VHS-Recorder would be enough to copy Macro-content, because it doesn't mind about the copy-protection.

As far as I understand it - Macrovision works by turning the sync pulse before the video burst into a whopping pulse which cuts in the AGC and pulls the video level right down. This does'nt change the playback into a TV as it is not effected. - however when you try to copy onto a recordable media it drags it down to a level which is too small. Old VCR's did'nt have AGC & so are not effected. You need to defeat the AGC which is quite difficult in modern kit as it is usually all in an integral I.C. - or run the signal through a processor which strips and re-lays the sync pulses.
A load of rubbish really as it can easily be defeated and quite cheaply these days. Processor in U.K. maybe 40.00.
Happy Ripping
