problem w/DTS-HD master on receiver UPDATE: fixed

[kurt vidal]

Hello,
I'm new to this forum and am looking for some help regarding subject.
I'm running a PS3 using an optical digital audio output to an older Pioneer Elite VSX-24TX reciever for my surround system.
I've got my PS3 audio output set to bitstream (not pcm).
My reciever is capable of showing me graphically if I am: A) getting a digital signal, B) whether its AC3 or DTS, C) which of the surround channels are being output, & D) if the output is in dolby digital (5.1) or dolby pro-logic (2 channel).
When I play a movie (ie: kingdom of heaven or league of extraordinary gentlemen) that uses the DTS-HD lossless audio format my reciever is showing its getting a digital signal, however, its only putting out in pro-logic mode (2 channel).
When I play a movie (ie: superman returns, evolution) that uses either "DD AC3 5.1" or "LPCM 5.1" my reciever shows I'm getting digital signal, AC3, all channels are being output, and I'm getting dolby-digital 5.1 (5 channels). This is the way a normal DVD would output on my system (non-blu-ray).
Can anyone explain to me why I would not be getting 5.1 channels while playing a blu-ray with the DTS-HD lossless audio format?
Any recommendations or possible workarounds that anyone could provide would really be appreciated.
Thanks,
Kurt
