Kodi skin setup with Live TV

I have a android MX3 2gb version tvbox for clients. I used to have a app with live tv channels but now want to integrate it in Live TV from Kodi. But my m3u list is buffering when used in kodi regulary and on vlc not. Also it need to be looking nice and easy to use. And I need some way to update plugins/theme/settings from distance (like kodi installer) because I have many clients. I have some skins I like but maybe you have something better
