How do I encode the DVD so that copies cannot be made from the disc, and the files cannot be downloaded? I'm using StudioPro 2. Thanks very much. - Rob

Macrovision or CSS?
Although I've never done this, DVD Studio Pro supports CSS (Content Scrambling System) and Macrovision. You cannot encode them to DVD-Rs. Generally those have to be written to DLT tape. You may also be able to write this to Authoring media using an Authoring DVD drive. There's also the Cutting Master Format which also needs a DVD Authoring drive.
There's some info in the DVD Studio Pro manual about this. Do search in the pdf for CSS and Macrovision.
One Copy Permitted?
There is another feature mentioned on page 558 of the manual. It's called "One Copy Permitted." It allows one to use the master disk to make copies but one can't make copies from the copies. I have no idea how this implementation works. Can I set that and send it out for duplication/replication so all dups (or replicated discs?) would be good but enduser couldn't make a dup of the dup? Anybody ever use this feature?
There's also the fact that just about anyone with a computer can rip a protected DVD with all sorts of freeware or shareware utilities. For that reason I'm just not sure why this is even attempted . . . and probably why the HD formats are "threatened" with much more annoying protection.
I have a corporate client who is thinking about this so more knowledgeable folks please do jump in ASAP.

there is NO copy protection on disc you burn. CSS and Marcovision are applied at replication, you pay for Macrovision and it an analog protect against VCR copying, CSS protects against digital copying.
PLEASE understand - they virtually give NO protection, if it is on a DVD it can be ripped.

[msacci]"there is NO copy protection on disc you burn."
I KNOW that.
[Craig Seeman]"You cannot encode them to DVD-Rs. Generally those have to be written to DLT tape. You may also be able to write this to Authoring media using an Authoring DVD drive"
You MUST make DLT or Authoring disc (on an Authoring drive). If my client WANTS to pay for it, I'll provide the service if I can rent the gear. I was wondering if anyone here has DONE that and can describe the process of checking the DLT or Authoring disc to confirm its function.
I'm also asking about the ONE COPY PERMITTED feature mentioned of page 558 of the manual. Apparently you CAN use this on a DVD-R but the manual isn't clear at all.

As the others who have already responded have said, there is practically no way that you can stop people from ripping your DVDs.
This means that if you are mastering disks for duplication, you have about as much security as most commercial DVD you can buy (i.e none).
If you are doing custom work for a client (low runs of burnt DVDs), then the best way of helping the honest customers stay honest is to customise the DVD as much as possible for them, so they are feel that copying the work will lead to their name being associated with the duplication. A nice menu saying something like "Created for Acme Corporation for use at their Head Office in Springfield. Disk #123. Duplication prohibited. All Rights Reserved" may cause hesitation if it is being shown at Baker Corporation. Put that on the label if you can so that only blind people will have an excuse that they didn't know they should be copying it. An individual's name burnt to disk makes it even less likely that it will be illegally duplicated, but try to make sure that someone can't just top and tail your video to eliminate the customisation.
