You don't mention what receiver you are using...THAT determines the sound field. Does it support DTS?
I have a BD-P2550 conected to a LN46A650 via HDMI 1.3 cable. I couldn't get DTS Master HD audio to work on the movie Transporter 3. The trailers and menus all had sound, but when the movie switched to 24hz and starting to play, there was no sound. I finally had to watch the movie in my PS3.
Also, why is there no support information or firmware updates on the Samsung site for the 2550, only the 2500?
Thanks =)
