The recording strategy that the drive follows during writing is based on specific instructions embedded within its firmware posrtion of code.
The software, normally, has (or shold not) have any access to this. (Except of informative messages about the location of speed reductions taking place.)
It seems, in your case, this recording strategy is based on the type of recording format. (Nero uses a different one from the other software you are using.)
It might also be the case that your software explixitly requests, before burning starts, your drive to follow a more conservative algorithm.
In this case, it should offer the user an option to shoose so, if he likes it... and not decide by itself.
