did 10.5.3 changed -R DL to +

I don't think 10.5.3 changed the firmware.

MATSHITA DVD-R UJ-867:

Firmware Revision: HA13
Interconnect: ATAPI
Burn Support: Yes (Apple Shipping Drive)
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -R DL, -RW, +R, +R DL, +RW
Write Strategies: CD-TAO, CD-SAO, DVD-DAO
Media: Insert media and refresh to show available burn speeds

Did you repair permissions after the update? I have seen read/write permissions messed up by software updates. Sometimes repairing permissions will fix this sort of problem.

Good luck!

My drive never burned -R DL it always stated only +R DL as you see below, this is before and after the update to 10.5.3,

i notice your superdrive is MATSHITA DVD-R UJ-857, mine as a D on the end of 857 so your superdrive maybe different then mine and did burn -R DL, someone that has the same superdrive as yours maybe will send you a reply.

Good luck in sorting out your issue

had the issue, it started randomly. your super drive needs to be replaced probably. if your warranty is still good it will be covered

Hi Sascha and others with similar issues,

You might find the very extensive coverage of disc burning issues in the thread at http://discussions.apple.com/message.jspa?messageID=5661178 useful.


When disc burning becomes a problem after an OS update two common causes of the problem are:

1) installation of the update on a system that had some underlying system or directory corruption - running Disk Utility from your OS DVD or an external HD to "repair disc" and repair permissions and then re-installing the update using the downloadeable "Combo update, rather than the SU version, will often fix this.

2) Insufficient or fragmented free space on the drive causing problems with the "disc image" that is cretaed during the burning process.


Cheers

slightly misread the original post

my issue was with normal DVDs not dual layer. but my issue was fixed with just a super drive swap (the new one doesnt sound as good as the original one with the boot up and initializing cycle but its much quieter)

is it just this one disc which is causing the problem, Sascha? How does the disc perform in your other Mac, though even if it works fine in the other one, it may be that your notebook drive is less tolerant of dirt or scratches, or some such.

What sort of disc are we talking here? Data? video? etc.

Has anybody figured an solution? I am having the exact same issue:

1. leopard 10.5.3
2. verbatim DVD+R DL
3. can't burn using the builtin DVD burner.

It's macbook pro 2.33GHz model. I tried using an external DVD burner, and burning is successful, however I have trouble using the built-in burner to read it. The built-in burner spins and reads some of the files and crashes randomly.

In such a situation, if the disc itself is clean and unscratched, I would try cleaning the drive with good disc cleaning disc, Sascha. It is not uncommon for a speck of dust on the lense or something similar to cause read problems, especially with DL discs.

Some drives are more "tolerant" than others, though, so make sure the disc is clean first.

Cheers

Rod
