When watching Transformers HD I tried the setting at Mpeg/Pcm and it seemed, louder/gruntier, but the surrounds didnt seem to work, well they worked but more like in mono.
Switching back to Dolby and the surrounds seemed to work just fine, (sound whizzing round etc).
I tried optical and the same thing happened, now running through hdmi. I was mainly curious if this is a sky thing with the pcm setting or something else?
Thanks in advance.
