There is a version that supports Dual Layer, and one that dosent. (1.3R2 does, 1.3 dosent). Can I use the 1.3R2 version which supports Dual Layer on regular dvds that ARENT dual layer? or will it not work? I have used it on about 5 of my game back ups and dont know if they will brick my wii, or if I am safe and dont have to burn them again. Thanks a lot!!
