Dude, so much AD here, why not clean them all?

Hello. I used to have the same issues till I switched dvd media. I have never used Ridata so I will not comment on them but try some of the new MAxell 8x disks made by Hitachi or Verbatim data life disks 8x also. If you check out the forums on DVD Media I think you will get some better answers there.
