Superdrive refusing to read burnt discs.

Hi i am writing this on behalf of a friend who has recently purchased a MBP. he has noticed that the superdrive refuses to read discs that have been burnt on another machine. it reads original company discs happily but when a burnt disc is inserted the MBP believes that the disc is blank and then asks what to do. The discs have also been checked in other machines and function correctly.

The only possibility that i could think of was to reinstall OSX however this would involve quite a large amount of reinstallation. Can anyone think of an alternative explanation/solution?

Is this a new MBP or did he purchase it used? Can it read disks that it burned?

And, why is it that folks seem to want to re-install the OS whenever something goes wrong? I thought that was only a Windows thing?

Regards.

The MPB is 6 weeks old. it cannot burn discs so consequently cannot read them

I would bring it in and have them look at it. It probably needs to be replaced.

If it can't burn disks, there is something wrong with the drive. Bring it back and get it replaced.
