Also there's a new firware from yesterday. It might be a good idea to redo the testing and check if they silently fixed DV playback.
I ran the sequence I normally do - play each of the makemkv.com test files in sequence - P4, P5, P7 FEL, p7 MEL and P81.
On the first pass - all 5 played fine - looked good. Diva reported frame rate switching and LLDV signal being sent.
I also "stopped" a few roughly 1/2 way through. System went back correctly to non DV mode and rate switched back to the default I have set (59.9Hz)
Looked good so far - never saw the dreaded Spinning Wheel of Death.
On the second pass, P4 played fine, P5 started with a black screen - but Diva reported that the stream was LLDV.
At this point, every file just displayed a black screen - but again, LLDV signal and frame rate switch would be shown as expected.
Now the interesting part. I then played a few SDR and HD10 videos - played fine.
But, any DV - mkv, mp4 etc. displayed a black screen.
So, exited Kodi and tried the native Netflix app. Played a DV video - black screen. Did show switching to LLDV mode - but all black (and sound was fine). Also, subtitles displayed correctly...
Played a non DV video - fine.
At this point, I read about Plex reporting a "Dolby Vision decoder crash". This appeared to be the case!
I needed to restart the Shield to get DV working again.
As @MrMagic said, this has been reported (by Plex and others) and in fact Shield@nvidia has said they are looking at it.
Crossing fingers that a fix by NVidia will at last get this working!
(Of course, I am ever the optimist ;-)
