If you are rendering them out as mono files then you need to change your project settings. Change your settings to stereo, move any audio sliders that are set to either left or right to the center. Then mute every track apart from the channel you want to render as a mono file. When rendering make sure that "enable multichannel mapping" is unticked. Set your output to wav mono and render. Then do the same for each channel.

I think that is the only thing I did not try, can your project settings be changed after it is done? I mean I have all my edits done and project saved but it is 5.1 settings.
