Use beta 8.95.1 or current Milhouse build.

Do you know what is actually the reason why some hardware supports it or not?

I believe this has something to do with the clock generator logic.

Wasn't that general issue with Kodi?

Some hardware is not capable of smooth playback of video with fractional frame rate like 23.976Hz. For example, all pre-Haswell Intel GPUs play 23.976Hz video at 24.000Hz and you get a repeated frame every 40 seconds. AMLogic also had this issue (but AFAIK it was fixed with some kernel patches).

I was wondering if Allwinner hardware is capable of properly displaying 23.976 fps video. I can't test this myself because I don't have the hardware (yet).

How well do those Allwinner devices handle fractional frame rates? Are there any issues?

jernej Do you have any ETA when deinterlacing will be implemented?

Save EDID to a file (tvservice -d edid.dat), copy it to /flash, and put hdmi_edid_file=1 in config.txt.

DVBSKY S960 works fine with LE 8.2.5, at least with a Pi3B.

Try the latest Milhouse build + updated tvheadend addon.

What UPnP bug?

That image will not work. Old kernel and old firmware.

It may be a good idea to open a bug report here. Include all the relevant info, a file sample and a debug log from Kodi 18.

It should be tested on a current build of Kodi 18. I can check if it works on a current Milhouse LibreELEC 9 build if you upload a sample to Google Drive, Dropbox or something like that. Or you can install the latest Milhouse build (or v8.90.009 ALPHA build) and test yourself.

Can you upload a small sample?

Use DVI to HDMI. But how do I get audio?

Did you try it? Not sure about your Foxconn NT3700 but modern videocards can output audio over DVI as long as you use DVI to HDMI cable.

I'm currently using kernel 4.19.7 with the "MUTEX_FLAG_HANDOFF 0x00" hack on a Raspberry Pi3 and it works well. Kernels 4.8 and 4.9 also work fine.

Well, it didn't pass the antenna cable "hot unplug" test that I do to accelerate the tuner failure.

@jahutchi I get this build error

This looks suspiciously similar to this issue.

I found a workaround for the mutex issue. It seem to be impossible to revert commit 9d659ae14b545c4296e812c70493bfdc999b5c1c in kernel 4.19, so here's a solution:

diff --git a/kernel/locking/mutex.c b/kernel/locking/mutex.c

After applying this patch the random tuner failures are gone. Tested with DVBSky S960, kernel 4.19.7.

What is your gpu_mem setting?
