Playback issues w/ CCwGTV (HD)

[TheDreadPirate]

The main difference I see is that one has Dolby Vision 7.6 (works) the other has Dolby Vision 8.6 (doesn't work).

For the record, The CCwGTV HD does NOT support Dolby Vision. Only the 4K model does.

I am wondering if the Avengers file (which is the one with DV 8.6) is not tone mapping and the DV data is being sent to the CCwGTV. I suspect that the DV 7.6 video (The Benghazi video) is being tone mapped since DV 7 is generally only supported on bluray drives.
