I had audio glitch sounds in playing some MKV files, then i found yify-torrents, and he encodes his own MKV which are drastically smaller yet still HD quality, none of his MKV files freeze or cause issues, all playing very smooth on the tablet, you might want to give it a try!I just realized it has to do something with sw and hw decoding... :/ in flac files and some mkv files I had the same problems, when I switched to sw decoding (I only found this option in mx player ) it seems to be working fine. Not all mkv can be decoded in sw though, 1080 seems to have trouble decoding on the slow sw decoder... I tried playing video with hw and audio sw decoding and I also see straing, maybe the sw decoder isnt fast enough to decode just dts on its own..
