I know the S6200 and S7200 will only decode 2CH for True HD. But how about Dolby Digital? Does these players fully decodes Dolby Digital or do they decode only 2CH as well? I have a an old Sony soundbar that that does not decode any of the HD Codecs so I have to relay on the player to internally decode these as LCPM. My S7200 fully decodes HD Master Audio as LCPM and sounds really nice but for True HD, I'm only getting DD. Does this means it's decoding DD as 2 CH only or Multi?
