You’re good, Alison,

RipGuard is designed to protect the CSS encryption. No CSS, no need for RipGuard, in other words.

Hi Guys,

When Roman Voska, owner and principle of Media Chance and DVD-lab PRO says the program is ‘not for professional use’, he’s merely stating what Apple, and a few other DVD authoring tool manufacturers should also be admitting 🙂

I’ll have more to say (with verifcation reports and playback testing results, observations, etc.) about DVD-lab PRO at another time.

Take care,

Thanks Scott,

Yes, the disc has other logical issues, but no unreadable sector/SCSI errors or warnings; which is what makes this one a bit tricky. I believe your analysis of imperfection at that location is correct, and I’ve got to be able to prove it to a replication broker (not as knowledgeable and technical as you are), which is hard to do if both their and my (on a ‘reference drive’) comparison tests have shown all the data on the Master is on the replica.

The discs are in the mail, and look forward to your findings.

Thanks again,

Trai

Hi Scott,

We’ve got a soft read at the spot that looks like is causing problems (these results are consistent across several different replicas); here’s Layer 0:

I’m able to get a byte for byte compare of the Master to the replicas, but only if I’m using my Eclipse approved “reference” drive (Plextor PX-716A). A couple of other DVD writers I have drops some sectors (at that spot, about 3 gigs in) during the transfer to hard drive, and the compare between master and replica fail. Problem is, the replicator also gets a byte for byte successful compare, and their limited playback tests have not shown the playback glitch, so they’re reluctant to redo the run (they’ve offered a reduced rate redo).

I tried to look you up to give you a call (you mastering guys are always deep in the ‘DVD cave’, it seems! :-), and am sending you two of the replicas by mail (you have a CATS system, right?).

I’ve learned a lot on this one (no more declarative statements from me till I see the materials, no matter how much fun it is to guess!), and would certainly appreciate a better understanding of how to navigate a case like this (the replication broker is acting measured and reasonable). If this were a check disc, I would have politely refused it, requesting new glass masters until I got steady reads across the platter and could consistently transfer all the data off.

If you have any questions please let me know,

Good to talk with you Alan,

After getting off the phone with you, I immediately added quite a bit to the first page of the “Why Verify the DVD?”
article (not quite putting what I was orginally thinking, though. 🙂

Everyone, please wish us luck. We’re possibly going to need some with this replication broker!

Hi Alan,

Well, the last job brought to me submitted on DVD+R DL had this issue! (good thing I don’t charge unless I find the answer and solve the situation, eh? 🙂

What you describe below is definitely a manufacturer error; try copying the disc to HD on another Windows machine, if you still get that copy error at the same location, you’ve got em (be sure to have snagit ready to grab a screenshot of the copy error messages).

If you get the same error on another Windows machine’s drive and you’d like some heavy artillery, send me one of the discs, and I’ll run Eclipse ImageAnalysis on it which will find the errors and document it nicely. I’ll send you the report in PDF form (that’ll get em for sure). No charge (but you might want to consider resubmission on DLT when the replicator agrees to redo the run. I’ll make you a deal there :-).

Take care,

Hi Alan,

You’re layer break isn’t occuring on properly flagged cell, or on a cell, even (known as the split-cell error; players don’t like it, for sure). Now, it’s a question of whether your replicator honored your formatting. But it’s most likely your formatter didn’t honor your intentions, or you didn’t have any, i.e., account for the layer break in your project.

The replicators “independent” test won’t check for what the problem is, so you’re about to get another “we’re not at fault” statement. And Bill is absolutely correct on this as Eclipse and DCA Image Analysis software do not support dealing with Images on DVD+R DL discs; so mastering with it is a crap shoot (for other more detailed reasons, as well).

I’d love to get involved in this one, but will stay in my corner until I’m officially invited.

Sorry you’re having issues at the plant,

Hi Dan,

Alex is right. Sonic Rom Formatter is pretty much useless for those working on the Mac.

DVD SP 4 added support for pure DVD-Rom formatting, which should preserve the resource forks in the image. Although I haven’t tested it, the process is outlined in the manual starting on page 575.

You can also use Toast to write the image, then move it over to the PC for Gear Pro Mastering (excels with ROM only material) to write the DLT (older versions of Toast can be used to write a DVD-5 size project to DLT). Even DVD-9 pure DVD ROM’s can be formatted this way. I have tested this method, and used it for years to preserve Mac resource forks and it works great.

Please let us know (Sorry for the late reply, it’s been awhile since I was over here in the DVD Authoring forum; I thought all DVD authoring was done in DVD SP! 🙂 <---that's a smiley Take care, Trai
