Please help GSA2166D

I bought this bumb thing over the weekend and I now feel like I need to
go back to school. I finally got my region code problem figured out, thanks to the forum for that. Now I can burn, rip and watch DVD’s. Buuuuuuuuuutttttttttt I can’t do anything with a regular CD. The drive will not recognize them. Not a blank CD/R not a Data CD/R and not a store bought audio CD. Any idea’s before I set fire to this thing???
