Protecting/Securing the data on your DVD-R?

[brvid]

Is there a way to "secure" the movies you burn to your DVD-R's, similar
to the way the movie studios make it impossible (difficult) to make a
copy of a movie you rented at Blockbuster?

If so, can you explain what's involved?

Thanks.

[SLK001]

Yes... Keep it locked in a safe and never loan it out. That is the most secure method.

[brvid]

I'll assume you're joking.

The scenario I'm suggesting is one where you create a DVD-R with
material that you're selling (i.e. instructional tape), and you don't want
the first buyer to be able to make further copies of that material.

Is there no way to do something similar to the disc like they do
to the movies you rent to prevent you from being able to make copies?

I realize there are "cracks" for just about every security procedure for
people who really want to access the material, but is there any
such security software or plug-ins for personal DVD burning to prevent
"easy" copying of the data?

[deadbeet]

no u cant. but good answer from above like it.

[defense]

@brvid, SLK wasn't joking....the average Joe can't just encrypt their own disks. I believe I read you could do it with Maestro but you needed all sorts of hardware..etc....and I know it can be done for hundreds of thousands of dollars...unless you have that kind of cash to spend....forget about it.

You might want to private message "BJ_M"....he could give you more specifics on this. Otherwise...follow SLK's advice...that's your only other bet.

[brvid]

Not the answering I was hoping for, but I appreciate the response.

Thanks!

wow...heard that from somewhere...could it be the MPAA stomping all over fair use... hrm....

anywayz, DVD-R authoring might help (as opposed to DVD-R general)...however, the authoring discs are like $15+ per disc...

[defense]

@poopyhead, I gotta admit, you really pull "POOPY" out of your head...and do so on a regular basis. The poster wants a way of basically encrypting DVDR's and that isn't going to be done easily.

DVD Authoring disks aren't going to help them any...because first of all...DVD Authoring disks use a different wave length to burn them. They ALSO need a special professional burner to burn to the DVD-AUTHORING format. The standard burners such as the Pioneer series: A04 05 AND 06 AS WELL AS THE SONY BURNERS......AS well as all other consumer DVD burners won't burn the DVD Authoring format because of this difference in in the burning wavelengths between the two formats.

But even IF the original poster went out and purchased these expensive DVD-Authoring disks, they'd still have to go out and purchase a professional burner to burn these Authoring disks. And even spending all that unnecessary money is going to help them how?

Keep em comin'.....

You could add macrovision, but it's not very effective at copy protection, but then again neither is CSS

[flaninacupboard]

let's see,
first up $2500 for a copy of CCE
next is $40,000 for a copy of scenarist
then a DLT to export it to (any ideas on cost?)
then a minimum run of...... 1000 discs being pressed? congrats you now have a disc that anyone with a computer and the internet can copy.

I wonder if you could create a "null" area of the disc, a blank video file that no options on the menu select for instance. then, work out where that data is on the physical disc, and punch a hole in it. you woun't be able to rip the disc as .iso and perhaps not at all. doable?

[BobK]

I would think that if there's an easy and effective way to do it then the movie studios would be using that instead of spending money on CSS and Macrovision.

[flaninacupboard]

there is an easy and efective and cheap way. travel back in time to 1994 and in the meeting going
"so, what size shall we make these DVD thingies?"
say "how about six inches, that way they won't fit in computers, and can't be pirated as easily?"
"excellent idea! here, have a million dollars for your trouble!"
"thanks! that'll help pay for my time machine!"

[SLK001]

say "how about six inches, that way they won't fit in computers, and can't be pirated as easily?"

You obviously don't remember 8" floppy disks and drives. If these things were 6", there would be 6" players and 6" recorders (and think about how much more bytes would be on them!).

[flaninacupboard]

No, I don't remember 8"drives and floppies. perhaps they weren't very popular because of their size...?
Yes players and recorders would exist, but they'd be expensive external solutions.

Trying to merge a data format and a video format was a bad idea.

[BobK]

Yes players and recorders would exist, but they'd be expensive external solutions.

Why would they be any more expensive than what we have now? DVDs were not made so they'd fit the drives in our computer, the drives in our computer were made the size they are because that's the size that DVDs are made.

If you went back in time and got the size of DVDs changed to six inches then you'd return to the present to find that all the DVD drives made for computers are made to hold 6 inch discs.

[poopyhead]

@defense,

you are such a **** up...

i was giving an example of how a DVD-R could be encrypted...you dumbass...

as the poster mentioned that it's for a training video...obviously, he's gonna be distributing it for professional purposes....

PROFESSIONAL PURPOSES...not some stupidass kid like yourself...

[freestyler]

If you premaster your authored disc in Gear Pro DVD you can specify copy-protection settings. Might be a good idea to contact Gear Software for further info, I'm not quite sure how / if it works.

Bob,
The point of a 6" disc is that the drive wouldn't fit in a PC's 5.25 bay. You'd need to buy a new case to fit an internal drive. how many people would have bought a new case and a new expensive drive just to use these 6" disc thingies that are for movies anyway?! Not as many as buy a pc from PC World and go "oh, it has DVD" afterward.

poopyhead,
My sentiments exactly! But then again defense doesn't see the link between science, film cameras and lenses........

How long have DVDs have been around? Since since 1995 or earlier. How many of us are using computers more than 2-3 years old? If DVDs were bigger then the standard size of a computer case and/or drive bays would have changed to accomidate them.

[spiderman2k1]

If people can back up and HollyWood DVD and ever DVD can be back uo and if there was some thing that worked. You would see ton's of people say how do I copy this. Every DVD can be copied.

[flaninacupboard]

from the DVDdemistyfied FAQ: . The first titles released in the U.S., on March 19, 1997.

So not 95

No-one would spend the £100's required for a new case and an expensive and rare DVD-ROM drive to watch DVD's on their PC.
People bought the drives when prices dropped, and because we were told again and again that not only can we watch DVD movies, but that all software would be on DVD before long.

My point is that if they made DVD's non-compatible with PC's both in physical size and by not creating a DVD-data format, there would much lower piracy levels.

[BobK]

So not 95

Okay- 97, not 95. How many of us are using computers more than 5 years old?

My point is that if they made DVD's non-compatible with PC's both in physical size and by not creating a DVD-data format, there would much lower piracy levels.

My point is that if they make something that uses a digital format then computers made after that will eventually incorporate the hardware, software, drive bays, etc to use it.

No-one would spend the £100's required for a new case and an expensive and rare DVD-ROM drive to watch DVD's on their PC.

And in 1982 no-one would spend $1000 for a VCR to watch the expensive and rare movies released on video tape. (I paid $1000 for my first VCR and blank video tape were around $18 each.

[flaninacupboard]

No, they wouldn't.
Have you ever seen a minidisc data drive? no? well i can tell you for sure they don't come in every computer sold.
Did you ever see a laserdisc drive for a PC? no? well they existed. why didn't people buy those and rip movies back in 99? because they were rare and expensive, like a PC compatible DVD-rom would have been.

So are you telling me that every custom built, and every major manufacturers' pc has been shipping with DVD-roms since the launch in 97? they haven't.
My first DVD-rom drive was my burner, less than six months old.

As for the VHS issue, it's a moot point. VHS never was and never will be directly compatible with a PC.
But let's use that as an example. DV is a great format, the tapes are cheap for the amount of storage you get, but how many pc's do you see come equipped with a DV-Drive? any? no.

[BobK]

You're missing the point (and apparently don't understand much about manufacturing and marketing).

Actually I haven't seen a minidisc data drive. I've seen ads and pictures, but I haven't seen one and don't know anyone who owns one- and that's exactly why you don't find them in PCs- because there's no market for them. But if CDs and DVDs didn't exist and minidisc was the only medium available then you'd seen a lot of them in PCs. Same for laserdisc and DV- they're not popular enough to make a profit putting them in computers. But if they were the only digital storage available then we'd all have one.

[flaninacupboard]

ok, whatever. i've no desire to start an argument.

It took a long time for CD-roms to come in Desktops as standard, and laptops took even longer. New technology does take a while to filter through.

Same for laserdisc and DV- they're not popular enough to make a profit putting them in computers

Eaxactly! If DVD was a Video only format (like laser and like DV) and there was no data version, it would not be popular in the PC market, hence not profitable. PC-DVD drives would be both rare and expensive. Only serious pirates would but them and the burners to go with them, your average consumer couldn't do a thing with them.

[solarfox]

Did you ever see a laserdisc drive for a PC? no? well they existed. why didn't people buy those and rip movies back in 99? because they were rare and expensive, like a PC compatible DVD-rom would have been.

(a) LaserDiscs are not a digital format (the audio tracks are, but the video is stored in a frequency-modulated analog format).

(b) No, there never were any laserdisc drives for PC's. There were laserdisc drives that could operate under the control of a PC; i.e. they could be told to start, stop, skip forward and back, etc. under computer control.

Actually I haven't seen a minidisc data drive. I've seen ads and pictures, but I haven't seen one and don't know anyone who owns one- and that's exactly why you don't find them in PCs- because there's no market for them.

Mostly because Sony stupidly sabotaged their own format by splitting "audio" and "data" into two separate, physically-incompatible forms. If they'd had the wit to make the MiniDisc a general-purpose device, and hadn't been so paranoid about copy protection and whatnot, they could have taken the removable-storage market away from IOmega (and Syquest) years ago with a product that stored 150Mb on a cartridge that costs about $3.00.

To this day, they continue to sabotage their own product by refusing to provide any means for the new NetMD-capable MD portables to upload audio to the PC, as well as download it.

As for miniDV drives on PC's, there's probably not much of a market for it because it wouldn't provide any useful advantage over existing tape drives. The market for tape drives as a whole is fairly small these days; home users just don't bother, and professionals or IT administrators are going to spend the big bucks for the high speed and capacity of DLT.

[flaninacupboard]

I know it's analogue, but it could easily be represtnted as digital. i.e. because all you are measuirng is the length of the pits this number can be digitized with a value of 0-10,000,000 (giving you your 5mhz badwidth) so theoretically the data could be directly reproduced. using one of the computer controlled drives, it would be possible to replicate the data. If the technology was still in use for new releases today, i'm sure it would be happening.

Yep. wise move that stopped piracy. oh look, that was my point all along......

[SLK001]

That's not how a laserdisk player works. It shines a laser on the particular track, and the reflection is read off by a detector. The laser is modulated by the pit structure to get the modulated signal (it is a lot like an old vinyl record player). So, there is absolutely no digital video information.

[flaninacupboard]

it is too how it works! (apologies for the poor pic. no image editing software on this machine!)

My point is that the pit will -always- be within a range of length "1" to length "10,000,000" with discrete values. therefore a digital representation can be had, simply by recording the number for each pit.

Edit:
Forum doesn't allow bitmaps, even if they're under 50k. oh well....... I made the text a hyper link to an image that shows the structure of the pits. the associated webpage is here
