DVD?s made with 10.4.11 cannot be read with 10.6.4?

by robintetlow / July 2, 2010 10:33 PM PDT

I have unusual, although not debilitating issue with DVD?s made on a white 13-inch MB (MB2,1, mid-2007, 2.16GHz, 2GB RAM, SuperDriveDVD=Matshita DVD-R UJ-857E) running Tiger 10.4.11 which cannot be read on a MBPro 15.4-inch (MBP4,1, early-2008, 2,4GHz, 2GB RAM, SuperDriveDVD player=HL-DT-ST DVDRW GSA-S10N) running SnowLeopard 10.6.4.

The DVD?s were burned, a couple of years ago, on the white MB and contain a copies of files from my user (administrator) directory, mostly iWork and MSOffice files.

I am able to read the contents of the DVD?s and open the individual files on the white MB but not on my MBPro: when I insert the disk, a finder window appears saying I have inserted a blank DVD and asks me how I wish to proceed in using it.

There many ways to recover the files, not least using the MB I created them with, but I would like to understand why this is occurring. Anyone have any ideas?

(NT) What method was used to burn the original disks?

I used the burn function of Tiger (Finder)

Apologies for not putting this information in the original post.

I created a burn folder first then dragged and dropped the files I wanted to copy to disk into it. After that, popped in a blank DVD and followed the instructions.

(BTW, I can read DVD's created from PC's running Windows XP on both Mac's)

I was wondering if the DVD

was finalized.

However, if they are created in the way you say, they would be automatically finalized.

Do you have any DVD's of a different brand that you would try on the MBP and then the new machine?

There would appear to be no difference between DVD makes

The three DVD's involved are all of different makes.

Focus please on "finalized"
by R. Proffitt Forum moderator / July 3, 2010 11:14 PM PDT

"finalized", finalized and finalized.

While I want to avoid a dissertation on file systems and CD/DVD recording, I want to focus on the word finalized.

Try that!

Having focused on the the word finalized.....
by robintetlow / July 7, 2010 6:33 PM PDT

the DVD's are in fact finalized and readable by Mac's running Tiger and PC's running XP.

The problem still remains...i.e. they are not readable on a Mac running Snow Leopard 10.6.4.

Has anyone else got some ideas?

Thanks again for your assistance.

Bad DVD drive?
by onemoremile / July 9, 2010 8:39 AM PDT

Can your MBP read other DVDs? If the DVDs can be read by other computers, then they are not the problem. You may have a hardware issue with your MacBook Pro. If it is still under warranty, I would definitely advise contacting Apple.

Yes, the MBP plays DVD's and CD's; commercial (films) and non-commercial (burned).

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
