Here's the situation: My late 2008 alu unibody macbook doesn't accept dvd's anymore. They load fine but before the system attempts to read them, it spits them right out. I googled for the problem, fond an article in the KB advising to reset pram, which I did. After resetting the pram, the dvd loads and is mounted, then spit right out, impossible to read anything from it. On subsequent attempts (without another pram reset), it just loads then spits it out, no mounting. CD's work just fine. My guess is the 'super'drive is toast. What do you guys think? Of course it's out of warranty....first my battery gave out after one year and one month, now this. Seriously disappointed about component quality, I could accept this from a low-end laptop but not from apple, with the premium they charge. Any suggestions? How much would a replacement cost (approx)?
