Buffer underrun protection

Hello,

i have following problem:

my cd-combo has a write speed up to 52x but if I burn a cd with 52x I’ll get the error message buffer underrun.
The datas to burn are on my local c:\ drive.
If i burn with 4x there are no problems.

where can i set a flag/bool for buffer underrun protection?

thanx…

Pass NBF_BURN_PROOF as flag to NeroBurn().
