Need configuration help!!!

[odogg10]

My setup is a pioneer vsx40, samsung bd-c6900 blu ray player, and samsung 7100 led tv...Now I used to hook up my ps3 and play blu's through there. I have hdmi running from tv to receiver and all hdmi's everywhere else. The question I have is that when audio used to display on receiver dts-master audio would be displayed. Now dts master audio scrolls across the screen but ends up only lighting as dolby true-hd...I know both are pretty equal, but am I missing something in terms of getting full audio capabilities. Am I losing anything through the way in which audio is being outputted? Also what are the ideal options on both tv and blu ray player to successfully accomplish this task. I believe I have the blu ray player as bitstream (audiophile). Also what options on receiver? I didn't think I needed to change anything on there because it worked just fine before...Please help?!?!?!?!
