Ubuntu 8.10 CD/DVD Creator won't burn a DVD

Binary package hint: nautilus

I am trying to do a data backup onto DVD+RW and it will not work. CD/DVD Creator gives me an error message when it tries to erase the disc: "There was an error writing to the disc: Unhandled error, aborting". I tried with Brasero to erase the disc, and it goes for a little while then brings up the same message. Worse though, now my disc is apparently unusable.

I never had any issues burning with 8.04. I am using Memorex DVD+RWs that I have used before. I'm trying to burn 4.2 gigs on to discs that have 4.7 gig capacity. I have tried more than one disc, so it's not the disc. My memory is perhaps low at 512mb.
