"When you say mutichannel format"

Just to make sure. No not the fact that yes you are playing a multichannel format ie: a DVD-A etc. But - beside having the DVD player set up for it in its menu. The Outlaw 950 has to have been in a multichannel mode such as DD, PLII before you hit the 6-channel direct button. If the 950 is in stereo mode (last setting you used) when you hit the 6-c button, you won't get your multi-channel analog.
