I'm having problems

I'm trying to do what you said and I thought I've made all the settings correctly but when I try to burn tony hawk 2 and e-surfer I get this error :
17933 (CDB: 2a00000001c 200001000, Status: 040002, Sense: 052100) Buffer under-run

Please what do I do. I've wasted like atleast 20 cd's by doing this.
HELP!! Please
