Strange DVD compatibility issue – check disk will play on DVD players, but NOT on DVD players (different result for check disks from DVD author and replicator)
Hello Everyone,
Our DVD Author created a DVD dual layer project for us, and we are experiencing this weird computer DVD player compatibility issue:
1) the project was created as a dual layer DVD, on Scenarist
2) Our DVD author’s check disk (which he output from Scenarist WITHOUT CSS) plays fine on both computers and stand-alone DVD players.
3) He then output to DLTs (and the only thing that was changed was that the “CSS” checkbox was checked, and the sector size was changed from 2048 to 2052)
4) When we took the DLTs to the replicator, they sent the DLTs to a “Stamper House” who made a glass master.
5) The Replicator received the glass master, and then tried to make a check desk, but they were having issues with their DVD-9 pressing machine, and they brought in an engineer and fixed the issue after 2 days.
6) Here’s what is strange: when they made their check disks from the glass master, and we tested the check disks, the check disks play fine on a stand-alone DVD player, but would NOT play on 3 different computers (including one Mac G5).
So, my question is, what could have caused DVD Author’s check disk to play fine on computers, but the Replicator’s check disk NOT to play on computers?
The Replicator’s glass master “Stamper” reports back is a DLT fails for some reason, but they were able to play the DLTs on their system.
Does anyone have any idea what could have changed from the time that DVD Author’s check disk played successfully on computers and DVD players, and the time that the Replicator’s check disks play successfully on DVD players but NOT on computers?
I appreciate your help and thoughts very much, since I do not want to go through the expense of outputting another DLT, having a new glass master made, and having new replicator check disks made.

Sounds like the replicator’s machine broke to me…

Thanks for your feedback,
But, is there anything in the replicator’s pressing machine that would create a checkdisk where their DVD plays on DVD players, but NOT on computers?
What’s strange is the the DVD Author’s checkdisk (without CSS) plays fine on everything.
The Replicator is telling me that it must be an issue with how the DLTs were made.
Thanks for your help in trying to figure out what exactly the issue is, and what step along the way caused the issue.

Hello…
I spoke with the owner of the Replicator house (who I have been told is also a DVD author), and he mentioned that while outputting to DLT, there should be a CSS option to 1) allow for playing on a computer (but no copying), and 2) disable playing on a computer (as well as no copying).
My DVD Author is using Scenarist 3.0 or 3.1… Has anyone heard of these CSS options for Scenarist or any other DVD Authoring software?
Also… Would it be possible for the Glass Master Stamper house to have incorrectly changed CSS settings when they made a glass master from the DLTs (the DLTs were flagged for CSS).
Thank you for your help…
My DVD Author and I are stumped.

I wanted to include an update about the newest pieces to this puzzle…
I took the Replicator’s check disks to our DVD Author’s office, and they DID play successfully in 4 out of 5 of their Macs, including older Macs.
(So, it looks like CSS is not the issue).
Interestingly enough, the one Mac at the DVD Author’s office that would NOT play the Replicator’s check disk, is a G5, just like my G5 that would not play the Replicator’s check DVDs.
And, again, our DVD Author’s check disk (which is exactly the same as the Replicator’s check disk, except that it does NOT have CSS and has sector sizes of 2048), DOES play successfully on all of our computers.
Thank you again for your help in trying to solve this mysterious issue.

We have both 3.0 and 3.1 and I don’t believe there is any such setting.
If there is it is well hidden. I’ve never seen it and I just looked again to be sure.Dave

When you say “won’t play” do you mean that the disc won’t even mount on the Mac desktop or start the DVD player? Or does it start the player but not play the disc?

Hi David,
Thank you for your feedback and thoughts in helping us try to figure out what is causing this issue.
To answer your questions:
1) On my G5, when I insert the Replicator’s DVD check desk, I receive a “-36” error from the G5 DVD player(which says that the disk may be scratched or dirty), so I assume that it does mount. On my 2 HP PC Laptops, the title of the Replicator’s check disk DOES appear after I insert the disks.
2) Thank you for answering the questions about the options for Scenarist. My DVD Author said that he didn’t recall any additional settings like that either. (It was the owner of the Replication company that mentioned that there were this in-depth settings for CSS, like “play on DVD player, but not on computer,” etc…
What I am asking the Replicator to do now, is to repress new check disks from the glass master, so that we can eliminate whether the issue was in the last pressing of the replicator check disks.
I am not sure whether there could have been an error in the creation of the glass master, but I don’t feel like spending $200 just to check that theory out.
My last step would be to ask our DVD Author to output NEW DLTs, without CSS, and then try to create the DVD glass master and new check disks with the new CSS-less DLT tapes.
What’s mysterious is that our DVD Author’s check disk DOES play on computers, while the Replicator’s check disks do not (granted, the Replicator created the glass master and check disks from the DLT tapes that were outputted with CSS, and the DVD author created his check disk without the CSS setting – and 2054 sector size – added).
I appreciate any other thoughts in helping us try to resolve this puzzling issue.

Hi Dave,
I just tried to play one of the check disks given to me by the Replicator on my Mac G5, and the DVD DOES mount on the desktop, and the Mac’s DVD player tries to play the disk, but like the other check disks from the Replicator, I receive a “-33” error, and an error message saying that the disk may b scratched or dirty, even though it is a new DVD check disk.
Thank you for any more thoughts you might have to help us resolve the issue…

Hello Everyone,
My DVD author posted this same issue in another forum, and a DVD author thought that the issue might be that the Replicator did not recalibrate their Replication press after they had to repair the DVD-9 physical molding a few days ago.
Although I spoke with one of the Reps with the Replicator, and she told me that they created another set of DVD-9 check disks for another project the same time that they created ours, and I am told that the other project’s check disks were fine. (But, I am not sure if the second project was tested on a computer).
Could this be an issue of recalibrating the Replicator press, even though our check disks do work on stand-alone DVD players, just not on computers?
Would a mis-calibration of the replication press result in a DVD playable on DVD players and not computers?
Thank you again for your thoughts,
Khashya
