I've had this imac 27" i5 for just about a month now and I've been able to both play and write CDs and DVDs just fine; until now. About two days ago I found this thing called ilife in my bag o stuff that they handed me at the apple store and figured i should install it. So i threw it in and let it do its thing. Once I was finished I went to put in a DVD from my new boxed set of one of my favorite TV shows (a christmas gift). A boxed set that I had already watched the first two discs of on this very same computer. It spun and spun, and then spun some more, and then spat the disc out. So I went looking for answers and found this: http://forums.macrumors.com/showthread.php?t=348900 No luck there. So I go back and put in discs one and two from the boxed set, and of course they don't work either. I am, however, playing a CD in this machine as I type these words. Any Ideas?
