if you want multi-channel sound from the built-in mediaplayer just play a dts movie on the tv and then go into the menu and set sound to dts. for tv sound in multi-channel you need to set it in menu broadcast as well. weird thing is this cannot be chosen while it is not playing anything with dts or dolby digital sound in it. you can only set dts2:5 when it is on external speakermode also. hope this helps you.
