Hi, I've been happily using CloneDVD for a couple of years now. Recently, for the 1st time, I tried using the DVD-5 option to condense the entire DVD contents onto one DVD-R. (Prior to this I always used the DVD+RL option and split the DVD contents onto two DVD+/-Rs. This always worked flawlessly.) Anyway, I started using the DVD-5 option and I've noticed that =sometimes= I get stutters and dropouts. Usually they are at the beginning of the disc and sometimes it clears up. Sometimes it doesn't. But what I've noticed is that it happens a LOT more with some DVD+/-Rs than others. IOW: it seems as though some 'batches' of blank discs are crappier than others. So... 1. Are some brands known to be better than others in this regard? 2. Is there some way to 'pre-scan' a blank disc and tell if it's going to record properly or not? 3. Is there some error checking in CloneDVD which can check that the data was written properly? 4. Are DVD+Rs intrinsically more reliable than DVD-R's? (My burner can use either?) Thanks!
