Suitable DVD for my drive??

[Princess_321]

I have a ''DVD/ CD - RW'' Drive but everytime I want to burn a Sony DVD - R the drive doesn't recognize. It's the same in all cases that means all such types of DVDs (n not just one).
I have to burn some movies so tell me which kind of DVD should I use for my drive.
Need you help desperately!!!!! Please!

look like you might have a combo drive, burns cd's plays dvd's , won't burn dvd's
