EVERY device have bug.........
, if you waiting a perfect media player ... you became very very very old.
3d ghosting it's not all film and not with all tv/ 3d glass
audio drop it's random and 1-2 time when playback film, with tv series there aren't.
it's little bug ,try another box ... it have big problem or less function , no 3d or no HD audio or no 23,976.
the other way is htpc with kodi, but different price.
