In some cases, Blu-ray players which previously were plugged directly into TVs with only stereo speakers will continue to limit their audio outputs to what the TVs could accept (stereo PCM), even when they're subsequently plugged into a more capable audio system. A full reset of the player often is necessary in order to clear out the old player configurations.
OK gang finally some progress. Here's what happened:
I tried power-cycling per JD's suggestion - but NG
I then did the factory reset on the Denon - looked like NG (at least when testing using the Sony CX960 changer)
Then bought another HDMI cable that was specifically labelled as HDMI 1.4a
I had a 2 yr old cable in the mix that said HDMI + ethernet.
Knowing that asarose's BDT220 was passing ATMOS content; I decided to get rid of some variables and troubleshoot using ONLY the new cable and the BDT220 as my source, and WooHoo SUCCESS at last !!!
I am now seeing the magic word ATMOS on the front panel.
Just for grins went back to the SONY CX 960 with the known good cable, but still no CX960 love with Atmos. Per Seldon's suggestion; I may try a full reset on the Sony CX960, after I watch a couple of ATMOS flicks
The lessons learned:
1) This Forum and community is your friend - Thank You All!
2) Be patient, take your time and logically eliminate the variables
3) Be sure of your HDMI cables and be the cable markings, they may not be what they are advertised as.
