View Full Version : Creating a DVD9 Glass master from DVD-R's

Hi,
I have a movie (approx. 6GB of VOB files) across two DVD-R discs.
Basically, I have a directory of 6GB in size, with a DVD movie, which I have placed on 2 DVD-R's.
I need to create a DVD9 glass master from the two DVD-R's and have been told that the source files have to be on DLT (2 DVD-Rs are no good).
Any ideas how I get the Glassmaster created from the 2 DVD-R's. Or how can I transfer the 2 DVD-R's to DLT??
Appreciate any assistance.
Most labs I contacted don't seem to have a clue.
Thanks.

Basically, I guess that you have to split the files on the dual-layer break and not on a specific file, that's why they ask you to deliver them on DLT, because each dlt contains L0 and L1.
I guess you can do this: Write on DLT and then dump the exact containts of each DLT tape on a DVD-R, but then again, if you had access to DLT, you wouldn't do that execessive step!
Anyway, you would probably need to create an image file of the VIDEO_TS directory, as usual, when dealing with dvd9's and then find/create a tool that creates 2 images from this image that are split across the dual layer break.
Don't know how this can be done without a DLT tape drive...
Yet, it's normal for the people working on glass mastering NOT to have a clue, since what you are asking is NOT the standard procedure.
Ans even if they knew how to do it, they wouldn't bother the hassle with what you're asking them to do, since, they would have to do extra steps.
And for my opinion, even if you find a way, which I would GLADLY like to know about, it's very risky, because DVD-R's are not that stable as you think. You don't want to have a call from the plant, telling you that the dvd-r's are not good, or even worse, that the 3.000 dvd's that have been pressed, are bad due to bad media...
I suggest that you should buy a DLT from eBay. You won't need anything more than a 7000 (5MB/sec). this means a full dvd9 takes 40min. I bought one for 300$ external.
And of course, don't forget that the application you author, should support DVD-9 creation and output to DLT.

I have now borrowed a DLT 2000, which takes DLT3 tapes.
Does anyone have any instructions and guidelines, how I should transfer my DVD9 project in Maestro to DLT?
Would I need to use 1 or 2 DLT tapes?
For DVD9, do I need to transfer in a special way, with the 2 layers?
Urgently need some help with this.
Thanks.

In the manual it's all covered, chapter 10:
10-36 Disc image creation.
10-48 Dual-layer discs.
You'll need 2 DLTs, one for each layer. You'll need to have a chapter set as the layer-break. You'll need to choose OTP or PTP etc.

Is there any chance you could send me the details on the process, as I don't have the manual.
or if you have an online manual, could you please email me the steps?
Appreciate this.
My email address is

Thanks.
PS. What is OTP and PTP?

OTP = Opposite Track Path. Second layer plays in the opposite direction.
PTP = Parallel Track Path. Layers play back in the same direction.
I'll contact you about chapter 10,

When I email you it gets sent back! I've tried a few times....

I have a similar (maybe exactly the same) question.
I have a 7.3 GB total DVD I authored, and I split the files onto 2 DVD-R's. It's impossible to turn this into a DVD-9? I will eventually need to send this away to a company for them to print, but since the Dual Layer burners aren't out yet (to my knowledge, though....) I can only do it on DVD-R. Is that still possible, with some changes? Using Scenarist.

Well burning(duplication) and replication are two very different things.
This is going to be a dvd-9 so I'd say you have to write to 2 DLTs, one for each layer or the rep house wont take it. Technically and I've heard stories, that it might be possible to go from two dvd-r's but I wouldn't recommend it. You might be hard pushed to find a rep house that will take this type of submission!
Scenarist has ROM Formatter built in so it might be able to do some things but I'm not sure... If ROM-Formatter is used I'm also not sure whether the dvd-video logo can be used on the disc!

These are the 3 steps required.
1) Compile (ALT+C) your project to a specific folder.
2) Select Disc Image Creation (ALT+D) and select at "Title Set Directory" the directory you compiled, NOT the VIDEO_TS folder. Select "Properties" and then check the radio button "Dual Layer" (this is the only time that you'll see these selections activated). Choose your desired direction of translation (PTP or OTP) and THEN select the appropriate chapter for the dual layer break. If you have selected the OTP (most likely) setting, bear in mind that the L0 has to be greater or equal to L1 AND less than 4,269,998,080 bytes. If there isn't any that comforms,(it sucks, but sometimes happens!), you have to compile again and create a dual-layer break point.
Let's say that in chapter 14, the L0 is lesser than L1 and at chapter 15 the L0 is greater than 4,269,998,080 bytes! You'll have to create a dual-layer break between these 2 chapters, so as to make smaller the L0 and still be greater than L1. This problem usually occurs when you have very little chapters and your project is very big.
So, if everything is fine, press OK and create the image file.
3) Select ALT+I and select your image and place a DLT tape in the drive. Don't forget NOT to have the write-protection on, because if you forget it at the second layer, you'll get an error and then you'll have to write again from L0!!
PS: You can skip the 3rd step, by selecting "To DLT tape" in step 2, instead of selecting "To image file"

That will help a lot! So it IS possible to make the masters on 2 DVD-Rs?
But that brings me to a new question. Do I need a specific burner for making these DLT's? Are they really expensive?
I'll need to send the DVD-9 size project away in a while, so I'm a little clueless.
As long as it can be done without a dual layer burner.

I have an idea.
If you compile your project in Scenarist 3.0, then you have the Tapeless solution. What it does is this. Creates 2 folders named "layer0" and "layer1" and in each it has several files needed by the replication plant, so it seems very logical, that if you write the contents of each folder in two DVD-R's, then you did it!
I'm almost 99% sure, that this can be done. Just double-check it with the replication plant.

DLT is not that dear. You can get them on Ebay for under $100.
You ideally need at least a DLTIII, as all newer models are compatible with these tapes.
It will be more reliable than 2 DVD-R discs, plus you can set copy protection flags which you cannot do with DVD-R media.
As always, check with the replicators first....
