Ok, I've got a pretty big library, probably close to over 500 movies. Previously I backed up all my movies to another DVD for general family use (borrowing etc) so they don't get damaged. Until recently I've used a PC for this. Most rips only had an error rate of less than 5% probably, and burns close to the same. Recently I've been using my new macbook. Of 6 rips, 2 were perfect, 1 had rip errors and 3 burn errors. I know this is a small sampling, but I've never had this kind of error rate before. Just curios what you thought. Is this just a streak of bad luck? Difference in quality of the macbook internal dvd vs my PC? Difference in ripping on the macbooks nvidia 9400 vs my PC's GTX260? Difference in ripping software MactheRipper vs DVDFab? Thoughts, ideas? I'm asking because shortly the PC is being gifted to a family member and being replaced by a iMac, so curios how your experiences are.
