Samsung dock is best supported by stock video player cause only this player sends video to hdmi screen receiver without playing simultaneously the video on tab's screen causing performance drop.
I tested NASA's 1080i video, SpaceX Launches to the International Space Station
without problem, with 5.1 channel audio enabled.
Also this player can support .srt files (same name as video, Greek language is supported without configuring something).
But i have faced many problems while using AVI's, MP4's cause video was not supported or analysis was poor or stuttering.
