Here's a few things you can try:

1.) Download Service Pack 3 for Creator 2009. This updates the software and is recommended.

2.) Update your CD/DVD burner drives. This can be done by going to the manufacturers website and checking for updates. (Ex: If you purchased your computer from Dell and it came with a built in burner, you'd check Dell.com for updates.)

3.) Update the PX Engine. This is Roxio software that communicates with the CD/DVD burner drives.

SOURCE: I have roxio creator & my dvd 9.0 de ; how do i burn my movies

I am trying to burn a movie onto a dvd using Roxio easy cd & dvd burning. The problem is that when I do burn it, it burns as a data disc. I try other things on it and it says to use the disc copier application to burn a dvd. I have searched everywhere on this progmram and there is nothing that says disc copier.

check roxio configuration the check if it is using the right drive.
sometimes the burner programs try to burn discs in virtual drives.
