Good day! long time reader, first time poster Bear with the n00b pls I read a bunch of threads and unfortunately I think it may have confused me a little more. I got a new rig (retired the 5.1 Sony receiver and Xbox first gen) for a PS3 slim and a new Sony receiver, STR-DN1000 My old receiver did not have an HDMI input and the optical out wouldn't handle the Bluray audio My question: I have some MKV files The issue (I think) is that the receiver keeps showing 'linear pcm' vs what I thought it should show which was DTS. The almighty blue light comes on signifying at least a 5.1 environment. I'm running PS3MS from the pc and streaming through the PS3. Using HDMI connection for audio and video, no optical cable. Is it just going to show DTS on the receiver when playing bluray discs in the PS3? My old receiver would show whatever the file was encoded with, perhaps I just need to RTFM for the receiver or is there a simple thing I'm missing? What other info can I include to clarify this more if needed? Thanks so much for any help / advice.
