I just want to sak you guys here to clarify something for me regarding aac audio. I like most people have a surround receiver that supports dd5.1, dts, pro logic etc. Right here goes: 1. Am i right in thinking that if I use an optical output on the ps3 the aac file will be downgraded to 2ch stereo. 2. If this is the case is there a chance that the ps3 could ever decode this and output to my amp in a fomrat that it supportS? 3. If not what would I need to get to achieve this as more and more of the hd clips I see have aac audio. 4. If none of this is possible is there a way to conver this file to an ac3 format without major effect on quality? Any help would be great Im just so confused and read many differing stories.
