I purchase a Maddog MegaSTOR 16x Double Layer DVD Burner in November of 2004. At the beginning I was using TDK 4x blank media DVD's to back up my home movies and everything was working fine. I have tried Phillips and just recently TDK 8x DVD's and after about 15 mins of burning I would get a writing error. I am at wits end with this issues. Anybody out there that has the same device and has been having similar issues. Or any ideas from anyone?
