Berseker are you saying that the Optical cable I have running to my AV Reciever to my Blu ray player will not pass Dolby True HD and so fourth? My Av Reciever decodes Dolby True HD and dts HD master Audio and its one of the reasons why I bought it. If thats the case then I am going back to HDMI!!! Now the coaxial cable that runs from my Directv box to my Reciever? I can live with that but when watching Blu's I need Dolby True HD and dts HD Master Audio. Let me know. Thanks.
