Got a strange issue with my DVD/RW....the system sees it, but when I insert a disk to either burn or an audio cd to play in iTunes, iTunes hangs or if I am using Toast Titanium the disk will not burn..here is what is shown in system profiler without a disk inserted, because if one is system profiler hangs as well, below is what is shown in "about this Mac":

HL-DT-ST DVDRAM GH70N:

Here is part of the code in the error message when iTunes hangs after trying to play an audio cd:

I would put the entire thing in here, but it is quite long and I can't attach it because it is in the wrong format.
