I have a panasonic F-35S DVD player connected to a Yamaha RX-V1400 via optical audio cable and a component video cable. I was under the impression that DTS sound was PCM sound and Dolby Digital was bitstream sound. I had my DVD player set to send DTS encoded material as PCM and Dolby Digital set to bitstream. When doing this my receiver recognizes the DTS signal as a PCM signal but will not recognize it as DTS. When I change the output signal on my DVD player for DTS to bitstream my receiver recognizes the DTS. Am I wrong in my thinking or is there something wrong with my DVD player or receiver? Thanks.
