I am running a P4 machine with 2GB of ram. I am running the following version of Roxio:

Roxio RecordNow Premier
Version: 3.0.0.
Build : 3.1.1a

I am using a Sony DVD/CD Rewitable Driver Unit Model No. DW-Q120A designed for Double Layer Disc.

Problem:
When I am in the Roxio interface I can see down in the lower left hand corner that I have an 8.5 GB disk in the DVD writer.
I am able to find the file I want to burn
The project begins and goes fine until at the end. At the end I get an error that there was a problem completing the project.
I am using Memorex DVD +R DL Double Capacity Single Sided media.
I have using 4 of these disk (ouch, they are pricy) with the same results on each burn.
Has anyone had success burning Double Layer Media with this version of Roxio?
Do I need a different software for this project?

Please Consult

Try updating your PX Engine (for the software) and the firmware for the drive.

Update PX Engine:

Update your Firmware:

Try reducing the burning speed as some media doesn’t perform as well at its peak burn speed and a slower speed decreases the amount of writing errors.

Also, make sure that you are using the branded media recommended by the manufacturer. Generic or "cheap" media has been known to cause a fair share of wasted discs and money for Sonic users. If you type in the model of your burner into the following link, it can tell you what kind of media you can burn to and what the best brands are to use, usually.
