Video playback stuttering, "vibrations" details etc.

In fact kodi output is automatically on 60HZ and compensates a vision without flickering but with famous micro-stuttering. Anyway I'm glad to know that you understand what I mean about that. Just an ultimate question for now  I noticed another issue regards the UI of player. Some apps installed not appears in "My apps" list. I have to launch them with an alternative launcher (that shows in the drawer) or with kodi. I also noticed that app preinstalled like wifi analyzer not appears.

I guess HiMedia have opted to hide some apps. Which apps?

Preinstalled wifi analyzer, mx player pro and zarchiver.

I could only speculate why those apps are hidden and I am choosing not to.

I read that pcristi has resolved in his custom firmware.

He has added and removed lots of apps. More info in the softpedia forum post for his firmwares. Link in opening post of custom firmware thread on this forum. The hidden apps don't do any harm. I suspect licensing issues is the reason they are hidden.
