Write error, write sector error on DVDR burn

[zappafan]

All of a sudden I am getting these two errors now when I try to burn. I just bought some new DVD-Rs so I thought maybe the media was bad but I also get the same errors when I try to burn to a DVD+RW that has always been succesful in the past. Here are my details:

DVD+-R/W Drive: SONY DVD RW DW-U12A
Operating system: Windows XP Professional
Processor: AMD Athlon 1800

Backup process: DVDShrink 3.0 Beta 5 Rip in file mode, select all files, rips from original DVD to hard-drive. Plenty of space on 120g hard-drive.

Burn using CopyToDVD 2.3.8.235

When the CopyToDVD finishes I get a small window that pops up that shows the two errors (write error, write sector error).

This is just a recent problem. Did I accidentally set something I shouldn't have? The ripped file on the hard-drive plays fine on the pc using PowerDVD!

Help!
