Burning with dj3 yielding TOC error probs

Hello, I am a newbie . I have been keeping an eye on the dreamcast/dreamcast emulation scene and finally decided to go out and get one (new low price, couldnt resist). I have burned a few games and have had minimal success, yet lately I am receiving errors. Ive made about 6 coasters from trying to burn 7 different games . The trial and error process sucks. I need help. DJ3 reports toc error and asks me to insert another disk once the first coaster is burned. I would appreciate any and all help. Thank you.
