I didn't have any issues playing 1080p SDR content but as I've recently bough a 4K (Philips OLED936) TV I've been playing as much 4K content via the Dune as possible and almost all at some point during payback experience a bout of stuttering several times at random points during playback and its got to the point where I'm going to have to abandon using it.
I can playback the same 4K content using TV's built in Media Player and Plex app without any issue, albeit they don't recognise the DolbyVision if in video track, just playing using HDR (Atmos is recognised).
The TV (which I can also connect with WiFi ac without issue) and Dune both connect using same ethernet to a NAS, so it can't be those. I've tried using Plex app on Dune but nothing at all plays with that.
Dune is on latest f/w.
I notice under the Android System Preferences there seems to be performance/network related settings but don't seem to make any difference.
Playback with less reserved buffers: disabled
Performance CPU mode: enabled
Under normal Video settings I have everything set to Auto (DV etc)
Under Playback Preferences , theres a HLS/Bandwidth: Auto (should this be set to high ?) again makes no difference.
So I don't know if it a basic Dune player issue or if it's the use of Dolby Vision that causing the stuttering?
Sometime I can "fix it" by stopping, waiting 30secs then playing again and it'll get past the stuttering, but you can imagine doing that a dozen times, is frustrating and impractical.
Either way, the family insists we never now use the Dune, which makes it not fit for purpose.
Has anybody had this stuttering or any suggestions ?

Using external subtitles with it?
-
Possibly on some but definitely not on others. But its stuttered on every single 4k film.

Not normal but watch your HDMI cable. Dune's run on the highest 60K framerate at 4K which is very demanding on the cable. Tried the cable coming in the box?
-
I am using a rather long ( high quality Blue Jeans) hdmi cable, but I didn't think stuttering was a cable symptom. Wouldn't it just be 4K at 24fps for films?
I've done several bitrate tests and the built in file read test seems fine. But I can try moving box onto a short cable. Cheers.

Always a good test. Yes I have seen audio dropouts caused by a cable. Audio is in the top frequency spectrum on top of Video and is jeopardized the first with cable bandwidth limits.

Does anybody know how to solve this problem?
