Choppy sound from Music Player topic

Choppy video playback on Note 3 topic

Since a bought the MHL adapter 2.0 (11 pins) from Samsung I have been trying to replace my WD TV mediaplayer by playing movies through the phone instead but every 1080p mkv file I try to play is choppy.

Players I have used are:
VLC player Beta
Diceplayer
BSplayer
Archos Player Pro
MXplayer
MoboPlayer Pro

None seems to work, my reference mkv file is:

"Escape.Plan.2013.1080p.BluRay.DTS-HD.MA.7.1.x264"

Size: 11.9 GB
Video: 1920x800
Bitrate: 9497 kbps (x264 High@L4.1)
Audio: English DTS-HD MA 7.1 Ch 5046 kbps

Thanks in advance!
