I've had very good results recovering old, corrupted/damaged, or bad burns, using "isobuster".

As a side note: At an Adobe seminar I went to, the subject of data back-up was discussed.
The experts (guess they were experts as it cost a lot of money to listen to them) was to convert all your files/data to one ISO image and burn that.
And (as BH said), don't try to max out the disk space.
