I use ljk, think someone off here recommended it and it does seem the best to me. The rest of the apps on my android box, such as showbox I use vlc as default but cannot get it to work properly on stb emu. If someone knows how I would give it a try. As to lipsink its mostly ok with ljk, the only programme I always seem to get the sinc out is RT News no matter what player I use but think thats the sub and its no great loss!
