2.1 to 5.1 audio when burning a dvd-possible?

I am not a computer genius and was wondering if there is anyway to change the audio format from 2.1 (which is what I have for my computer) to 5.1 dolby digital when you burn a dvd? I use convertxtodvd to burn the dvd’s and it won’t give me access to the type of audio i want, it stays at automatic.

Nope, you can only convert it with the right tools.
