Problems with burning, please help

Hello, I have been having problems recently with my burning rom drive “SONY DVD RW DW-D22A”.
It can not burn -R dvd’s, only +R dvd’s. I dont know why this occured. I didnt have this problem before.
Can this be solved with a driver or a patch or something ?

Oh, and the Autoplay feauture doesnt work either.

Welcome to CD Freaks.

The General Hardware forum is not the best for getting help on this so I’m moving it to the Liteon/Sony burner forum.

First of all, thanks and second of all :
Please help, I am desperate.
The Information state that this driver supports DVD + - R and still, when I put a -R dvd into the trey it prompts me to put a writtable disc etc etc.
