Appreciated. Hoping we can track down a few more. Meantime, I'm hoping some of you maintain a fairly large UHD collection and have 7.1 surround.
Do any of you own X-Men Days of Future Past? Simply an easy example, of many, to demonstrate clearly the concern regarding the 820 DTSHD-MA 7.1 or Dolby TrueHD 7.1 Bitstream to PCM conversion.
There's a fairly long Cerebro scene with lots of reverb ("echo"). If you convert the DTS HD Master Audio to PCM in the 820, do you find that the sound is messed up? As if there's a rear channel delay. The bitstream should be obviously fine in comparison.
I haven't tested this much, but it seems that native PCM 5.1 is being expanded to 7.1.
Separately, though related in that this is a dual-HDMI problem, is the inability of the 820 to play movies with seamless branching. There are only two clear examples that I have, but there may be more. Both are Sony titles - Leon and Black Hawk Down. Each of them will "pause" ("freeze") periodically for a few seconds before playing again. Hoping we can get confirmation that others have this problem.
Finally, I'll simply note, as an aside, that my former player Panny UB900 could not properly send DTSHD-MA 7.1 or Dolby TrueHD 7.1 bitstream when Atmos/DTS:X was included. I'd get rear channel sync pops during playback. Thought it was my AVP. Nope. (My work around was converting to PCM, which I was ok with, generally speaking). The 820 is performing just great with the bitstream (and, oddly, not the PCM!). I'm very pleased to send bitstream, of course, but there's still apparently some dual-HDMI problems.
