MACROVISION

jjulio1111 · Post by **jjulio1111** » Sat Jun 16, 2007 5:48 pm

There is in the FAQ: http://www.ulead.com/tech/dws/dws20faq.htm
"DVD Workshop allows me to put Macrovision in my ISO disc image and send the ISO file to either a DLT for replication or to burn as a disc. Is it OK to place Macrovision on burned discs?
The reliability of Macrovision on burned discs is less than on discs that have been pressed by replication. During replication, an encryption flag is set within the first 6 bytes of a sector, letting the DVD playing device know to search for Macrovision flags in the DVD content itself. Burned discs have no control over those first 6 bytes, so only DVD playing devices that continue to search for encryption flags, even though they did not see an encryption indicator in those first bits, will recognize the Macrovision copy protection.
Relevant Website:
http://www.macrovision.com"

Now I ask: Why? Why our DVD recorders can not write those first 6 bytes? Where are they written, at this the first sector?

It's because replicated discs have 2054 bytes per sector (as opposed to home burned discs using 2048 bytes per sector).

Currently, dvd burners cannot burn the CSS/APS because they are limited to the 2048 bytes per sector -- but that might change sometime later this year where we *might* be able to burn CSS on home made DVD's (the format was approved, but the burners, software, and dvd blanks will need to be able to work properly for this to happen). And there's still the licensing side of things (who pays -- users and/or the software companies

)

So it is written between the 2048-2054 sector?

Have you seen this? http://forums.murc.ws/showthread.php?t= ... acrovision

Have you also get this DVD program? If so, could you e-mail me?

Each sector is 2054 bytes vs. home made dvd's with 2048-byte sectors. The "protection" is written in the 6 extra bytes per sector.

You just have to keep watching for announcements on upcoming hardware/software/discs for this type of burning at home...

And what about this? http://www.arsenproductions.de/knowledg ... er_dvd.htm It can't write CSS, but it seems that it can write macrovision.

Yes, it doesn't say that...

What exactly is it writing -- a DVD-VIDEO (ready for playing in a DVD Player), or a master disc ready or replication

Can master disc also be played?

The Authoring / Replication facility will use the info on the Master (CMF Format) to create the final discs...

p.s. please don't double-post -- not sure why you posted a link that you already posted earlier in this thread (I removed the double-post)

As an user, have you ever get this agreement: http://jjulio1111.v10.com.br/imagem2.jpg ? Just like Jerry Jones luckly got one: http://forums.murc.ws/showthread.php?t= ... acrovision ? This agreement, in another words, is a program that they e-mail us, as I think that Jerry Jones received one attached in an e-mail?

Can a master disc be played in a DVD Player?

I don't understand. Why the http://www.arsenproductions.de/knowledg ... er_dvd.htm can write macrovision, but can't write CSS? And where are the DDP written, at the first 6 bytes?
