I tested with a advancedsettings.xml file (the same I created for SPMC 16, copy and paste in the local MrMc install folder, under "userdata"), and now 25hz files play fine ;)
You just have to add lines I posted on one of my last post in a file named "advancedsettings.xml"
Maybe something we want to bring into core then.

Which platform ? On tvOS, you can add one (via FileManager) but you cannot edit it or read it but the contents will be shown in mrmc.log during startup.
I was thinking for the shield. What exactly are the 25fps changes that supposedly make MrMC work better doing?

<adjustrefreshrate>
<override>
<fpsmin>24.96</fpsmin>
<fpsmax>25.01</fpsmax>
<refreshmin>24.96</refreshmin>
<refreshmax>25.01</refreshmax>
</override>
</adjustrefreshrate>


adjustrefreshrate means it only matters when "adjust refresh rate" is enable, aka display switching.

There are two sets of values, mins and max. It tightens up the band for picking 25Hz as the desired 25Hz display refresh rate.

My setup switches fine. Not sure why it's needed at all, maybe if I saw a debuglog :) The debuglog shows what the display can do, and what rate was picked and why.

OK, it's no use for me then since the shield won't switch to 25p for me anyway. If you recall what's been said in the off topic thread I made.

I will create a debuglog ASAP ;)

Here is the log file of my last test with 25hz serie issue ;)
It finds these display modes:

20:49:40 T:138601002064 NOTICE: Found resolution 1920 x 1080 for display 0 with 1920 x 1080 @ 59.940060 Hz

And setup for this when it sees a video with 25fps:
Display resolution ADJUST : 1920x1080 @ 50.00

So what's the problem again ? 25*2 == 50 :)

Yes I took a look on the log fille, and it's strange, because it's absolutly impossible to see the serie, a lot of stuttering every 2-3sec.
I look the same file on kodi 17 and everything is smooth.
Maybe a problem to convert 25 to 50Hz (2*50) for my sony 4K TV, because when I use advancedsettings, it works fine too like kodi 17 ?

There should be no difference as your hdtv cannot do 25Hz in the 1st place. I'd like to see a debuglog with the advancedsettings.xml addition. Maybe that will show the reason.

Yes, that's what I think too, I'm gonna create a log with advancedsettings.xml file soon ;)
