Pls excuse me if this subject has been discussed. Not able to find the right thread. To play Blu-ray movies with True HD audio, such as "DTS-HD" with an older receiver without HDMI connection, i can only use its optical or coaxial. Any advice how am I going to get surround if the Blu-ray has only "DTS-HD", and no other usual 5.1 options? The rear speakers were not activated when i played a disc with only DTS-HD, seems like I am getting stereo instead of surround.
