I have tried several of the media player apps available for the Avail, and so far, none of them work as well as I would like. All I am really trying to do is to watch regular H264, MKV or MP4 videos without needing to convert them. As far as I knew, the Avail should natively play all of those formats with its stock video player, but almost none work properly, unless I specifically convert them. Could someone recommend the best, smoothest media player for the Avail? MoboPlayer is way too choppy. The framerate is terrible. I can't recall the others off the top of my head. QQ Player was just awful. If not a decent media player, could someone at least tell me which formats of movies or video files have the highest compatibility rate with the stock player? Any advice is greatly appreciated.
