Hmm...if you know which file causes the error you can send it. I didn't test a DVD+rw but it doesn't play a role at all. You can try it even with a floppy disk ;) I guess it's somehow more related to a structure problem. If you got files on a different disk you could try that one, too.

I just rebuilt a full dvd of data and it worked just fine.

Guess we need more information about the actual files to find the cause of the runtime error.
