I use a hpBDDVDRW CH20L along with AnyDVDHD and have no current problems playing or backing up. While reading the stickys there was some info about the region setting. My current (has been for quite sometime) region setting is "not selected". Although I have no problems to report, I am wondering what may happen down the road with my "not selected" region setting. Should I have a definitive setting or just leave well enough alone?
