I have a blu-ray player that's HDMI, but my receiver is not HDMI. I connected them using their "coaxial" jacks. I'm getting "DSP" sound, but I can"t get "DTS". My receiver is "DSP/Dolby/DTS" capable and I get "DTS" when using an "optical audio cable" with my other DVD player that is DSP/Dolby/DTS capable. My blu-ray does not have an optical port. I'm using the same 5.1 DTS movie with both the blu-ray player and the DVD player. Is it possible that "coaxial" outputs/inputs do not transmit DTS signals? THANKS!!!
