I’ve burned a few DVDs with Nero 6.6 as opposed to Nero 7. There’s a difference in the actual burn; Nero 6.6 has a larger visible indentation closest to the center on all disks. Nero 7 (with functional DVDs) has a smaller disks of that sort.
Does that have anything to do with the corrupt DVDs made by Nero 6.6? Is there a way I can recover the data?
