Adjust refresh rate enabled. Sync audio/video disabled since it should not be needed on this hardware. Scaling to Auto, delinterlacing set off.
Watching a [email protected] video at 1080p... and I can watch the VSyncOff number start at like -15 and over the next 30 seconds work its way down to 0, and then I'll have 1-5 dropped frames, and the number will reset to like -15 and do it all over again. And then to top it off, I'll get random 5 second periods with massive dropped frames like (70-100). I can play those segments over again and they'll be fine.
Feeling like I should've stuck with v15.... sure, I had to reboot it every couple of days, but at least it could play 720p videos without dropping a single frame!

480p23 + AAC 2.0 + Lanczos3 = no dropped frames (vsyncoff rock solid at 0.0)
(...)
720p29 + AAC 2.0 + Lanzcos3 = massive dropped frames (vsyncoff fluctuates from -12.5 to +3)
So... looks like there's only problems with 29p (actual 29p) and 59i/p regardless of audio, but 59 is handled through skipping frames fairly gracefully, but 29p gets horrible stuttering periods making it unwatchable. I even have a 0.5mbit 720p stream that causes hundreds of dropped frames a minute.
I have exactly the same problems (25p and 50i/p are unwatchable too) with kodi builds after 15.2.
The 6.0.398-Intel_EGL build is the last that plays fine.

...So there are surely sync issues in that file (and thousand others) and the actual method to sync those leads to massive video stuttering. On 6.0.398-Intel_EGL there is no noticable stuttering.

Of course I can post the complete debug log, but these are the parts where the different behavior of CDVDPlayer and CVideoPlayer are visible. Or maybe its a difference in ffmpeg.
