just bought a tx3 mini few days ago to replace my ras pi2 as pi2 cant play h265 codec

some comments are:
1) the player like mx player or default player are totally useless (always no sound), just download and use vlc
2) youtube 4k 60fps seems having issue to play continuously, always video pause like every 5 minutes, need manual click to continue
3) astro go.. same as above many people had encountered, redirect back to login page

had read somewhere says mx do not have some codec but lazy to find and download as vlc can play my files directly
