Changing nero dvd burning speeds

Hi all, i have a problem! My home DVD player (denon DVDA 100) will not play DVD’s that have been burned at more than 2X for some reason.

My DVD RW is a Benq DW1620 and will write up to 16X, the blanks are 1-4x.
So when using nero i need to know if anyone can help me change the speed down from 4X to 2X, strange i know, everybody wants it quicker! :slight_smile:

Thanks in advance!

do you not get the option ->
