errr....first of all.....tis question might not applicable to u but hey ill just ask anyway...

1) does ur setting when u wanna burn is set to DVD instead of CD/CDRW???
2) does ur setting chose the dvdrw as the burner...???

if all this is set properly then maybe ur drive...but if drive prob...normally ull get a failed burn....

anyway....see la how...if its kaputt edi go rma...
