Burner problems

My dvd burner NEC 3520A burns everything on 8x now, DVD, CDS. He could do CDS on 48x before and DVDS on 16x i have updated my firmware to 3.06 and i use Nero Premium 7.

Somehow it got changed when i installed a different dvd burning program because my Nero (6 at that time) didn’t want to burn a .iso of over 3.6 GB i don’t remember the name of the program but it was a crappy one i just picked on fast off Download.com basically it was the one with worst rating when i looked later…

I tried reinstalling Nero, i changed my burner from Slave to Master, installed Firmware and it still stays the same.
