I have a question. I have QuickSilver Power Mac and its SuperDrive has been replaced number of times. Original DVR-103 lasted about year and a half, then died. Its replacement, Pioneer DVR-105, lasted about year and died. Then its replacement, Pioneer DVR-108, lasted less than a year and died. Needless to say, I'm somewhat disappointed with Pioneer product and I'm wondering if there is another brand that I can replace it with and still maintain iTune & iDVD compatibility. Does anyone have a recommendation?
