I replaced my Cd-rom/DVD player a month ago after it was giving me trouble. I bought a Superdrive on ebay and installed it. I'm still having problems though, and I can barely use it. I have to tilt the laptop back to get it to read or eject a disc. Do you think it's the drive or is it some other problem since I am on my 2nd drive? I don't have the money to have apple fix it, it's only 1.5 years old.
