I am seeing this problem in a number of forums on the net. I am having the exact same problem; can't recognize dvd-r, dvd+r DL, but can play regular dvds. Those updates have been coming fast and furious and it feels like they caused a problem. I went out and bought an LG GSA E60L external burner and it won't recognize blank dvds either. Bottom line is that it is not our drives and it isn't Nero either. I've had other situations like this before and then in a few updates the problem went away. This one is real frustrating and I am growing increasingly impatient with the authors of AnyDvd. As I said, this isn't the first time. DOes anyone know of competitors program that works better than AnyDvd? Maybe this is the best we can hope for.
