How can I burn each layer to separate DLT?

klimvid wrote on 12/20/2005, 2:43 PM

I have a 6+ GB video that I am having replicated on DVD9 media for commercial distribution. The replicator wants each layer of the DVD submitted on a separate DLT. I have a DLT system to which I have written single-layered projects for DVD5, but I am stumped as to how to write each layer of this current dual-layered project separately. Can someone explain to me how?

Surely I can't be the first person to run across this situation.

I need to send this project off tomorrow. Can someone please tell me how to burn each layer of a DL DVD using DVDA3 to a separate DLT?

Alternatively, can you suggest where I might find the answer to do this using DVDA3 if not on the Sony DVD Architect Forum?

Thanks.

Have you tried looking at the manual or online help? It seemed to cover this pretty well when I looked at it.

Thanks for your reply, Scott. I found nothing on writing separate layers to DLT in either the manual or online help. Have you done this process?

Inn the discussion on various options that you can specify during the mastering process, there's a selection where you specify how many layers (1 or 2) and which layer you are mastering.

After working through the dialogue boxes and initiating the Mastering process DVDA3 stalls out on the "Mastering Layer 1". There are two progress bars, the top one, Overall Master Progress, remains at 0%; the bottom one, Writing CMF 1.0 Layer to DLT, reads "Checking for tape content on tape" and stays that way for over two hours, which doesn't seem like progress at all.

I've tried 4 different tapes with the same results. The DLT unit is brand new and was used to successfully write master files for a DVD-5 a few weeks ago and that took only minutes, not hours.

Is this stalling on "Checking for content on tape" a problem with DVDA do you think? Any ideas of what could be going wrong?

ScottW wrote on 12/23/2005, 8:27 AM

There's an option to tell DVDA to erase the tape as I recall - try checking that option so it won't check the tape for existing content.

Scott, when "Erase the Tape" is checked the same thing happens, it stalls on "Checking for content on tape".

Do you know of another software that I could use to write the prepared files to two DLT tapes?

http://www.gearsoftware.com/products/gearpromastering.cfm - haven't ever used them though.

I'm surprised though that the replicator doesn't accept other formats - such as ftp or even a burned +R DL

klimvid wrote on 12/23/2005, 2:18 PM

Yes, I'm surprised as well, but after a day searching forums and FAQs it seems that few if any replicators will accept anything other than DLT. Don't ask me why, though, I mean I have the mastered folders on my hard drive - Layer 0 and Layer 1 - and I can't see why I couldn't just burn the files to two separate SL DVDs. Data is data, right? But for some reason replicators prefer working from two separate DLT tapes to make masters.

I am beginning to suspect that the DLT tapes I'm using from ebay have been formatted on a DLT 7000 or other machine thus making them incompatible with my DLT 4000 unit. I'll pick up two new tapes in town ($40 each, gasp!) after Christmas and see if that is the problem.

Merry Christmas to all and A Happy and Prosperous New Year!

A number of replicators do accept single layer ~masters~ on DVDR. However having all the files for a dual layer is often a problem on a pair DVD-ROM. If both sides are full- and there is the issue of error risk in the ISO9660/UDF storage format.

Whilst DLT is defacto - the other popular option is for removable/portable hard discs to be provided to the replicator. This is quite cost effective with 60GB removable hard discs being cost effective against single 20GB DLT.

If your replicator does, just check whether FAT32/NTFS or MacHFS is their preferred format. Whether you ever see the USB2/FW/SATA drive again is possibly not that big an issue. The DLT can then be your MSBACKUP recovery master. If you want long term reliable archival.

Yes, I have heard reference to submission on hard drive being an option. But the replicator I'm currently dealing with would then charge $150 to make a DLT from the hard disk. Go figure.

Problem solved. The used DLT IV tapes I was using were apparantly defective. I purchased two new tapes and DVDA3 performed flawlesly, writing Layer 1 to the first tape and then stopping and prompting to insert tape two, and then writing Layer 2 on the second tape. Thanks for all replies.

Hi Klimvid or others with experience with creating DLT from DVD architect:

I wonder how you finally went with the DVD pressing, and was that all successfully completed using the DLT tapes you produced from DVD architect?

We have a Dual Layer project which we compiled to 2 x DLT tapes using DVD Architect 3.0c, as easily as you described, but the manufacturer has come back with a problem with the tape:

*** " We had some problem about DLT tape of Australia From Space. When we load it into mastering system, it could not be transferred normally. We tried it many times, but it does not work. The system appears "Input short than expect", so we think it is problem of setting. Kindly please check this with the clients and send us new DLT tape ASAP. " ***

Not much to go on, so of course we will try and get more details, but I was curious to know what your (or others) experience was, and if you used any special settings on the drive unit hardware re compression etc?

Regards Lance.

TIP: If you don't have a DLT as part of your setup, there's no need to run out and purchase one. Just about every DVD replicator will now accept CMF or DDP, both of which are supported in DVDA 3. Exporting to either of these formats will result in a file that can be

a) burned as a data file (DVD ROM)

or

b) parked on a portable hard drive (usb or 1394).

Thanks, The tape is already with the manufacturer, so would prefer to find what the issue is.

I will check to see if they will accept the DDP/CLT file via DVD-ROM or FTP. However, they suspect that the issue is with the data structure within the DDP file, and not the physical DLT tape iteslf.

I have further feedback from the manufaturer:
* The problem occurrs on both layers (ie both tapes)
* The problem is that the claimed length (capacity) does not match the actual length (capacity), so the data cannot be tansferred to mastering.
* I have placed copies of screen captures of the ImageCopy the manufacturer sent report that shows the error as links here:

The only issue I can suspect myself (reading between the lines of the DVDA help a bit) is that I have set the 'copyrighted' setting in the DVD mastering properties, but have not set any CSS or macrovision settings - could that be an issue ? Ie, if copyrighted is selected is it then mandatory to set values other than 0 for CSS and/or macrovision?

I found another mesage from a member who had the same problem. with the mastering
