I think my drive is shotty, every time I go to burn a cd it completes 2-3 then it just keeps turning and skipping with a weird sound and spits the disc out and says can't complete burn. It plays some dvds but not others. There are no scratches or anything on dvds either. So I want to replace the drive what's a good one for less than 100.00? I want to play dvd, burn dvd, play cd, and burn cd...thanks for your help, I don't have the slightest clue about stuff like this.
