Ok im looked for a while before i posted and couldnt find anything so i hope someone can help. I have a ps3 hooked up hdmi to my receiver the samsung htas720 with 5.1 expandable to 7.1. I know the ps3 can decode dd true hd and dts hd master audio. I am just wondering how to increase my audio bit rate. I just watched the dark knight running in dd true hd and it was running on average about 2.3 Mbps. Dolby says it can go Up to 18 Mbps bit rate. I am wondering what effects the bitrate and how can i maximize it? Is my ps3 or receiver limiting it? Is that how much everyone gets with their setup because the disc only puts out that much? Does 7.1 put out a higher bit rate? Anything info helps ill even take a link if you dont want to explain. Thanks a lot.
