edit ~/.mplaye/config to that:

[evofile]
profile-desc="for EVO h264 encoded files"
psprobe=5000000

[dts6ch]
profile-desc="DTS 6ch mapping"
af=channels=6:6:0:4:1:0:2:1:3:2:4:3:5:5

[default]



then make "/usr/bin/amplayer" script and chmod it:

#!/bin/bash
mplayer -frames 1 -endpos 1 -identify -ao null -vo null "$1" > 
/tmp/media.status
_container=$(cat "/tmp/media.status" | fgrep ID_FILENAME | sed -e 
's/ID_FILENAME=//' -e 's/^\(.*\)\.\(...\)/\2/' -e 's/.*/\L&/')
_demuxer=$(cat "/tmp/media.status" | fgrep ID_DEMUXER | sed -e 
's/ID_DEMUXER=//' -e 's/.*/\L&/')
_vformat=$(cat "/tmp/media.status" | fgrep ID_VIDEO_FORMAT | sed -e 
's/ID_VIDEO_FORMAT=//' -e 's/.*/\L&/')
_vcodec=$(cat "/tmp/media.status" | fgrep ID_VIDEO_CODEC | sed -e 
's/ID_VIDEO_CODEC=//' -e 's/.*/\L&/')
_aformat=$(cat "/tmp/media.status" | fgrep ID_AUDIO_FORMAT | sed -e 
's/ID_AUDIO_FORMAT=//' -e 's/.*/\L&/')
_acodec=$(cat "/tmp/media.status" | fgrep ID_AUDIO_CODEC | sed -e 
's/ID_AUDIO_CODEC=//' -e 's/.*/\L&/')
_achannel=$(cat "/tmp/media.status" | fgrep ID_AUDIO_NCH | sed -e 
's/ID_AUDIO_NCH=//')
#printf "\n\nContainer\t: $_container\nDemuxer\t\t: $_demuxer\nVideo

if [ "$_acodec"=="dts" ] && [ "$_achannel"=="6" ]; then
     mplayer -profile dts6ch "$1"
elif [ "$_container"=="evo" ]; then
     mplayer -profile evofile "$1"
else
     mplayer "$1"
fi
