I have a hdtv, and a panasonic home system. I have the optical cable coming from the panasonic to the ps3 and I get surround sound for my games and movies. I watched Alexander blu ray and I got the full surround sound treatment. I have the settings on bitrate. I just bought True blood season 2 blue ray and when I played it , I had error reading on my panasonic. I went to audio settings and took off dts although my panasonic plays dts 5.1. I replayed true blood and it works but I'm not getting true surround sound. I have a regular home system 5.1 speakers, 5 speakers and a woofer. Now when I looked at the options in true blood audio , for audio it reads English DT- HD master audio 5.1. Am I doing anything wrong or is it just that my panasonic home system isn't equipped to play all blu rays? I know there was an update for the ps3 for DTS-HD audio.
