Reworked everything, finally.
Vizio set up is on its own power bar/surge protector. Sony set up ditto in another room.
Vizio set up is Cable Box (Brighthouse aka TWC) in then Analog audio L/R out to Earphones, with HDMI out, video only, to TV and Optical out, audio only, to Sound Bar. Blu-ray player is HDMI to Receiver then HDMI out to TV.
Sony TV is DTA in then HDMI to TV and Blu-ray connected to TV via Composite.
Phew. Now ... can I get the Harmony to talk turkey to the Vizio set up.
Oh yeah, got a 7 on the wife-acceptance scale.
