about how PCM audio works. I know it's uncompressed, but how do I know if my receiver is able to use it. I've got an Onkyo TSXR-605 and a Samsung BDP-1200 Blu-ray player. If I'm using the DTS-HD/MA or the Dolby TureHD it shows up on the receiver display. How do I know if I can use the PCM track, because every time I select PCM the receiver display says "Multichannel". I thought that was essentially the audio being split evenly between the speakers. Any help would be appreciated.
