I think a possibly easier way would be to write two shell scripts. One
for the dts with the correct command, same with the evo. Then you
would use those programs instead of the regular mplayer/gmplayer

ie

#!/bin/bash
# Plays DTS with correct channel mapping
mplayer -af channels=6:6:0:4:1:0:2:1:3:2:4:3:5:5 $1

Then do the same thing with the evo files. chmod them and give
everyone e'x'ecute then throw it in the /usr/bin

You can then set up your window manager under the filetypes to use
that program whenever playing certain files.

Good Luck
