I took video at a martial arts event, and sold the DVDs for $15/each. One promoter bought 20 of them, but he just called and none of them play on his DVD players at his home! I am using RiDATA DVD+R 16x disks, burned at 16x using a brand new Lite-On EZDUB burner, and NERO software. I set the 'booking type' to DVD-ROM when burning this. ANY IDEAS? What can I do to help the situation!? Help!
