I'm surprised how come the software didn't come with the drive. Actually its a good thing too, because at least this way you can use whatever you want. You can try Cheetah Burner
... one of my friends use it and they seem to be pretty happy with it. But I'm not sure about how good it actually is. Personally I too use Nero, because it came with my drive... and I'm too lazy to get anything else.
And of course, google is your friend when it comes to such things, but make sure you try and verify that the software does what it is supposed to do (i.e. it isn't malware or anything like that).
