I ve just got a denon 4308a and i am having a problem with uncompressed pcm 5.1! When i choose dolby dig 5.1 from the blu-ray menu the sound is good, but when i choose uncompressed pcm 5.1 the sound seems very mixed up! The centre dialogue comes out of the rears as well as the center. It sounds like the same sound is coming out of all the speakers instead of the ones they should be coming out of????! Sorry, but very new to this and i was wondering if there was a simple mistake i was making? Ive got it connected by hdmi from a sony 350 bluray player and dolby true sounds great! its just the uncompressed pcm! cheers.
