Writing lead-out problem ...?

Question

Writing lead-out problem ...?

Howdy All,

I am using iDVD6 to burn a project to RIDATA DVD+R DL discs. The burn in iDVD6 90% of the time fails at the end (no error logs). However, after playing the DVD on a number of players (computer and dedicated) the DVD seems to be fine (all aspects - movie, slides, finish etc).

A hint at the problem may be that when I use Toast to burn data to the same discs it fails at writing the "Lead-Out" with Mac OS Error -5001. Searching the Internet hasn't really told me much about either of those (Lead-Out) or Mac OS Error -5001.

Burns have worked fine on the Samsung TSSTcorp CD/DVDW SH-S182D DVD Burner before, with other media (Imation DVD+R DL). However, writing the lead-out also failed on an Imation disc when retrying it after it failed on a RIDATA disc. DVD burns the Imation succeed.

Would anyone have any idea of what is happening? Can I just ignore the problem? Is there any easy way I can do a bitwise compare of the DVD and, say, a disk image? Does iDVD do a verify of the burn (although having it tell me the burn failed isn't a good sign if it does)?

If this is a media issue, which I assume it is (although the Imation failing is a problem), what has it go to do with writing the lead-out?

Thanks in advance for any suggestions, experience, comments.

Cheers,
Ashley Aitken.

Hi Ashley!

For what it is worth, 'Lead Out':

Marks the end of each session on the disc.

On CD media it is the area that follows each program area. The main channel in the Lead-out area contains audio or data null information. This area is coded as track AAh.

The DVD Lead-out area is the area comprising physical sectors 1.0 mm wide or more adjacent to the outside of the data area in single layered disc for PTP (Parallel Track Path) disc. Or the area comprising physical sectors 1.2 mm wide or more adjacent to the inside of the data area in layer 1.

You don't provide any information on what Mac you have, what OS, how much RAM (example: see my profile at the bottom of this post), which would help a lot in diagnosing your problem.

Many here find that Verbatim DVD-R, as well as Fuji DVD-R, give the fewest problems, even more so when they are burned at only 2x or 4x.

Please post back with more details.

Hi Klaus,

Thanks for that, I kind-of guessed what "lead out" was about but thanks for giving all the details.

You don't provide any information on what Mac you
have, what OS, how much RAM (example: see my profile
at the bottom of this post), which would help a lot
in diagnosing your problem.

Power Mac G5 - original single CPU model (can't recall the speed) with 2GB RAM etc.

New Samsung DVD Burner (as indicated in previous post), original drive didn't burn dual layer disks.

I've since found that my "backup" with Toast (spanning multiple DVD+R DLs) that failed the Lead Out actually bit-compares with the original.

As the DVDs which failed also seem to work fine in DVD players and on the computer, I wonder if this is really a significant error.

Thanks that info - its unfortunate we have to burn at slower speeds than the drive is rated - kind of beats the purpose ...

I've previously had pretty good results with Imation DVD+R DL but wanted something that was inkjet printable (DL).

I could only find RiData locally. I now know that they are though of as second tier media, so perhaps the media is the problem.

Cheers,
Ashley.

That would seem to indicate a burn error - either faulty media (most likely) or the burner itself (unlikely).

As for burn speed, it is generally recognised that a slower burn gives a better burn, and serves to compensate for what may be less than perfect DVD coatings.

Yes, Imation are usually OK.

As for the other brands, have you checked (googled) whether they might be available in Oz by mail order?

If you think it has been, please mark this thread as 'answered' so that others mind find it.

Good luck with it all!
