Had some time to dig into the "Can the 4308CI make 7.1 via LPCM from 5.1 lossless?" issue I posted above.
As stated, on DD 5.1 via non LPCM source material it works fine, this is cable box:
You can see the on LH side DD5.1 is input, and RH side shows 7.1 is delivered to speakers via the PLIIx processing:
and under the audio menu, I can select PLIIx Cinema
Now, the PS3 comes up as follows when initially started, nothing running.
Full 7.1 "possible" via LPCM.
and under the PS3 Audio Settings I have it set this way manually, basically decode everything:
However, I can't select for the back channels how to process them at all if not 7.1 source, it only comes up with "DSCRT ON", which I'm guessing means Discrete On?
This is different than the page 82 led me to believe, or do I have a mis-understanding?
As a test, I put 2 blu-ray's in, first "Up", DTS-HD MA 6.1 (box says 5.1)
Check this out, it porcesses the "6th" channel into 2 for the back wall
Now, Happy Potter Ch 7 Pt 1 is DTS-HD MA 5.1
and is passed along as such, 5.1
So, either I'm reading the table on page 82 wrong.
Top say "input", and I look in the LPCM portion.
