Just double-checked on a couple DTS trailers, and it works for me. It could be that you told it your receiver doesn't support DTS? If you do that it'll change the DTS setting to downmix to PCM, which either does the front two stereo or a Dolby Stereo mix (decode with prologic) of the channels, either way outputs on only two channels. That can be fixed by going into the audio setup, and making sure that it's DTS=>DTS rather than DTS=>PCM. It could also be that 2 channel is selected rather than 5.1, but since you say it works with other stuff, that sounds unlikely.
Tried all the downsampling modes first since the 2 channel problem fit the discription. no luck
What I did find was this:
I have only a 4 speaker system(all large speakers). It appears that turning the Sub and/or center disables the rear channels for some DVDs like "Sting brand new day". If all speakers on, this DVD plays fine. For other DVDs like Lord of the Rings extend edition in DTS audio mode or "Riding with the King" in DTS mode, Center/sub configuration doesn't matter. It always goes to front 2 channels only.
All of this mess applies only to DTS. Dolby has no such problems.
Be interested to see what type of trailers you are using to see if problem is consistant
Huh. I used a few from the Widescreen Review DTS trailer disc and just let it run through a few while I did some other stuff. I also tried on a DTS movie a couple days ago and it worked. I'll try to remember to drop to the 6ch analog inputs on some other DTS discs and see what happens. You may want to contact pioneer support though and see if they have any known problems with this.

I just bought one of these today at best buy. Seem to have a problem with mine. The DTS 5.1 analog outputs only work on the front 2 cahnnels(digital ouput works fine).Dobly Digital 5.1, SACD and DVD-Audio analog all work fine.
Just wondering if anyone else has this problem.
