Won't play in a DVD player

I just ripped and wrote a DVD using Super Clone DVD and AnyDVD. Both of the discs were burned OK with no error messages. But when I place each of them on my DVD player, it won’t read it. What could be the problem?

I’m not farmiliar with super clone dvd (if you are using the free trial, I would consider other software), but one posibility is poor or unsuported media. What kind of burner do you have and what kind of disks are you using. Use dvd identifier to tell the media id on the disk, as what brand it is doesn’t tell much. What exactlly does it do when you try to play it?
