Windows Media Player Does Not Recognize CD/DVD Burner ("No CD or DVD burner has been detected")

I just bought an Inspiron 6400 with Sonic Media player and it may have removed some of my Windows Media Player functions.  I can't burn CD's with Media Player (I get the message "No CD or DVD burner has been detected").

 

Other players such as Real have no problems burning.

 

Another problem occured when I took a disk burned on my 6400, using Sonic Media Player, and put it into my 4 year old desktop.  It now has the same problem as my laptop:  Windows Media Player doesn't work on my desktop either (same message).

 

I bought the Inspiron 6400 for the sole purpose of music production (I'm a musician working on a CD project) and need Windows Media Player to work on both computers.  It seems like a simple problem to fix but no one seems to know what I can do (I have tried re-installing Media Player 10 and going up to Media Player 11 but the problem doesn't go away).

 

Any suggestions?

 

Thanks
