Without. Mostly typical 720p 4GB MKV files, it's not super obvious but It happens, you've already answered a few Q10 user about sync issues futeko, that's why I'm asking if the problem is from Kodi or Q10.
Regards!
There shouldn't be any big sync problems with Q5 and vanilla Kodi.
However, if you want the best playback please use the HiMedia native player via the wrapper.
Any problems there are, will be a combination of Kodi and the Q10, it's impossible to say 100% it's one or the another at fault. Kodi Android is developed for many chipset / OS platforms. It's not 100% perfect for playback in it's Vanilla state on any hardware. Please use the wrapper, which is developed specifically for the Q5 hardware.
