Opitarc DL DVD writer wont read audio CDs?

The Opitarc DL DVD writer built into my laptop refuses to read audio CDs.

I tried to rip a Cd i borrowed from my local library (it was factory pressed, an original) and in my computer my DVD drive popped up with the Audio Cd thing. However every disc i put in (blank, written, factory pressed ect.) my computer tells me how much space is on the disc. my computer tells me 0 bytes out of 0 bytes. when i double clicked the audio cd it told me windows could not access the device/path specified.

I even tried an original cd that I own and it didnt work.

i then put in a audio cd that i had burned to cd-r. same thing.

I wondered if my drive went bad so i tried a blank cd-r. it was ok. i then tried a cd-r with data writen to it and it worked.

I tried some original DVDs and those worked fine. I have no burned DVDs that my computer would read (computers cant read burned wii games) so i couldnt test dvd-r.

I tested a Samsung slim external USB DL DVD writer and it game me the same thing as my internal drive. So i dint really think its the drive. (but there is that possibility.)

Help please?

PS:

If it helps at all I am running Windows 7 home premium 64-bit version.
