For the longest time I have had a problem with my DVD Burner.
In korea I had a Sony DRU-510 and had no problems, but when I left active duty, coming back to the states I bought a new Sony DRU-530a and just couldn't get it to work.

Finaly last night as I was fooling around with a computer that had a bad HDD, I once again tackled this problem.
Now I feel stupid for not fixing it before.

In Instant Copy (my edition atleast) there is no "driver" for the DRU-530a.
So Set it as the DRU-510.
You may not record at the higher speed, but it sure beats burning corrupt disks.

I hope that this may be of some help to someone else.

I use: DVD Decrypter and Instant Copy 7, with my DRU-530A.
It works excellent.
