I am playing a film 1080p via ps3 media server to my onkyo 605 using an HDMI cable only. On the screen I can obtain 2 displays depending on how i use the ps3 media server, these are;Multi channel
or hdmi pcm dsp
MY QUESTION IS which one of the obove is the correct display for a DTS soundtrack
Please help me, I've read loads of posts but am totally confused
I'm not sure I understand the question, and I'm not sure I know what "screen" you are referring to, but I have played around with the different options in ps3mediaserver to get surround to stream correctly to the PS3, so hopefully this will help a little. These options are on the transcode page I believe of ps3mediaserver:
Multi channel PCM HDMI will decode the DTS track to PCM on the media server, and send the PCM audio from the server to the PS3. You need an HDMI connection. This process requires a lot of bandwith and also some CPU cycles.
There is also an option to decode the DTS to a Dolby Digital AC3 on the fly. This takes a lossy format and makes it lossier, but works well, and can output either HDMI or Toslink.
Alternatively the new version of ps3mediaserver (1.10.1 I think) can trick your receiver into decoding the DTS stream itself. The PS3 cannot playback a DTS soundtrack in a MPEG4 container, so it rewrites the header on the fly so the PS3 thinks its getting a 2 channel LPCM soundtrack, but when output to the receiver with a Toslink or HDMI connection, the receiver will know its a DTS soundtrack and decodes the sound itself. I have tried this with my Onkyo 605 and it works very well.
Hope this helps.
