external USB burner not recognized

I have a Dell Inspiron 8600 laptop with Windows XP Professional, Windows
Media Player 11. My internal CD/DVD burner stopped burning, so I purchased a
LiteOn external DVD writer w/Nero 9 software that connects via USB port. The
burner works fine, as I have burned CDs with the Sonic RecordNow! software I
already had on my computer. I installed the Nero 9 software, but I have not
played with it yet. The problem I have is when I try to burn a CD of music
files from my Media Player library using Media Player. Media Player tries to
burn using the internal burner, which no longer works properly. How do I get
Media Player to burn CDs using my new external burner? Thanks for any help.

Try going to Device Manager and disable the internal CD/DVD burner.
