I’m not sure that’s a problem specific to corelec etc. as I see this from time to time with disney+/youtube on my LG webos TV.
Suspending Coreelec is my solution. But it doesn’t happen when I switch from CE, generally only if CE was on when I turn the tv on.
My am6b+ arrived, loaded dual boot firmware on it and have it running.
Is there any way to expand internal memory allocated to CE? CE_Storage was created with 2.9GB size and my backup I want to restore is 7.5GB 
That’s probably one of the most heavily tested movies I’ve tried. Unique because it’s DV @ 59.94 hz, along with having lossless Atmos. As of the latest CE21 build it’s playing great on my Ugoos boxes. I
If you’re running Kodi at 3840x2160 and 59.94hz, try changing to 60hz to ensure it triggers a refresh rate switch (and set it to start/stop). And you need to make sure your setup can handle full bandwidth of HDMI 2.0b (~600Mhz).
Where I can find best dovi.ko file? 
Here
After 1100+ posts, admittedly it’s bit hard to play catch-up in this thread 
Exactly this 
It should be added to first post
Thanks a mill!
Do you know what’s the difference between dovi.ko that you linked to and the one provided by @YadaYada (YadaYada’s dovi.ko)?
MD5 hashes are different.
You’ve just solved @borygo 's request with your question. That’s the right thread about the dovi.ko from external sources.

@speedy seen you on the Infuse threads. Is DV Profile 8 on Infuse really native on the recent Infuse version and we should see no difference in playing DV Profile 8 files on Infuse and Ugoos?
Thank you very, very much. Changing the HDMI cable solved my problem.
What’s the preferred mode
Use Player Led should be on or off?
I’m not seeing this with my Apple TV, just with CE.
Interesting. Sounds similar but not identical.
The Ugoos is really great, and I can verify that FEL works (seeing the woman with the camera in EL_BL). All DV content I have plays, but I want to make sure this is right - when I’m playing DV content, it’s 8 bit RGV but BT.709.
Is that right? Shouldn’t it be 2020?
For non DV content I’m seeing 12 bit YCbCr.
Having the BT.709 or BT.2020 flag does not seem to affect the image quality. It used to be set to BT.2020 by default, but then that was removed from the code. Now it is set to BT.709 by the video source. There is a command line option to manually set the flag to BT.2020 somewhere in this long thread. Again, it doesn’t seem to matter.

For the colour flag it depends on your display/TV if older then maybe worth your while checking, see which you prefer if you see an actual difference if not then just don’t worry about it.
The TV model is less than 2 years old, so probably no older by your definition.
How do I change this in order to test?
