hi everyone. please help me if you can. i am backing up some films that i have onto piodata 8x super grade a media which i have been told is ritek go5 dye so i thought they would be good quality, although i am having to throw away more than 80% because they can not be read in my dvd player. nothing has changed from previous sucessful burnings except for the media. i would like to know if it is possible that my actual burner is broken. how would i know? it is burning cd's alright. any insight is greatly appreciated.
