about a month ago I bought a 40" Samsung LCD and have my ps3 hooked up to it via hdmi. everythiong seems to be going smoothly except when I borrowed a mates transformers 2 blu ray - when I play it all I hear is the background noise like music sound effects but none of the main sound like voices etc? not too sure whats going on....

also just a bit off topic anyone know how to play a video file with PCM audio? or do I need an amp to decode the sound. as im just playing through tv speakers. tried like every single media player and codec AC# coded files play fine.

thanks in advance!
