Having coaster problems with DVD+R9 media

[Cyde Weys]

I have seven ISOs I want to burn. They're all over 4.5GB so I'm using
dual-layer 2.4X +R media. I have a NEC ND-2510A burner with the latest
firmware update and I'm using Nero 7 Premium.

The first five burned perfectly. Then the sixth and seventh just
didn't work. I'd get all sorts of data verification errors in the
"checking data" stage after the burn process. This happened FOUR times
on both the sixth and seventh discs. Am I really unlucky or is there
something wrong with these ISOs? I tried mounting them with Daemon
Tools and ripping with DVD Decrypter - no errors were detected. So
why, when I try to put them to physical media, do I seem to always get
these errors?

Have you tried using them? I'm wondering if they contain
deliberately bad data as it was a copy protected disc...
though I don't know if that means the ISOs are worthless or
if that just means they would work but can't be verified
100% due to the deliberate protection, just as the original
wouldn't have been able to be 100% verified.

They do seem to work (at least somewhat), but maybe in just the minute
of testing I haven't run across the bad sectors. I guess I'll need to
watch them all the way through. That'll take a good amount of time.

And I thought that all data verification does is verify that the iso
was burnt correctly to the DVD? If the bad data is on the iso it's
also on the DVD, but it's the same bad data, so shouldn't verification
succeed since the files are the same? I don't think data verification
even cares if the data is "bad" for video or not - it just says, did it
burn correctly?

Of course you are! They are not meant to be used as coasters. They
don't absorb the sweat from the glass very well. I bet they even stick
to your glass of vodka sometimes.

Sorry...couldn't resist.

I have absolutely no sympathy for wussies that have to put their glass down.

I can't imagine DVD Decrypter allowing "bad data", whatever that is.

You might want to use DVD Shrink to compress the content and burn it
to a SL disc just to see if there are any problems.

BTW, is that particular DL disc resident in your NEC unit? DVD burners
maintain an internal table of "allowed" MIDs.

If you need a tool to read that table, check with CDFreaks. I have one
that reads only NEC drives and there is another one that is used to
alter the table and other internal parameters. Look for

Just be careful - you are messing with firmware.

First of all, I tried watching the discs that I got validation errors
with. They played fine most of the way through ... but there were
definitely errors in there that would give the DVD player software
conniptions. I tried watching those same scenes with the DVD ISO
mounted with Daemon Tools and it worked just fine. So the DVD ISOs are
good, but when I try burning them, something gets corrupted?

I also compressed the content down to 4.5GB, burned that, and it worked
fine. My best guess now is that I have a case of "shitty media". This
stuff is new, still prone to errors, and I've seen lots of complaints
online about crappy media.

I don't even know what you are talking about here - MIDs? Huh?
