Ok... So I have a 17 inch iMac flat panel...its rock solid...I love it it loves me...BUT Recently the dvd player is wonky. Old DVDs that i've had for a long time will play...but most newer dvds dont. I open the DVD player and it just says this DVD is unrecognizable and spits it back out. Its a superdrive...so it will still play CDS/Rip CDs. But the burner is also not working. Now I could really care less about burning CDs/dvds...I would just like to play DVDs in my machine....any clues/hint/ideas ? Also...if I had to get a new DVD drive...what are we looking at cost wise ?
