Alright guys, I could really use your help. I recently received the Sony HT-DDWG700 as a Christmas gift from my girlfriend. I set everything up and have my PS3 hooked up to it via an optical cable. I have set the Blu Ray and DVD options to output as Bitstream, but when I play a game, the surround sound system chooses to use PCM 2.1 audio instead of Dolby Surround Sound. Does anyone know what could be causing this?
