I would have mentioned that before ,but we had a problem to solve, you can make your own templates, by change the parameters and then giving a new name and saving.

I have templates fro 60mins to 180 mins with no audio and two pass and use the same AC3 sound for all of them, don't forget there is a Script that allows batch render so it will make the MPEG then go and make the AC3 while you go and do something else.
