Are you ready for this? Firstly, I am no newbie but I am utterly stumped with this and am losing the will to live. I have installed: MoboPlayer BSPlayer MXPlayer Zimly VitalPlayer iMPlayer+ RockPLayer Lite And I cannot get a single one of them to play any video!!!! I have used Freemake to convert .avi and .mkv to mp4. I have used H.264 for video and ACC and mp3 for the audio. I have downloaded and tried Leawo Total Video Converter, Handbrake, and Next Video Converter. And still I cannot get a format to play. I get a black bar on the screen telling me that the format is not recognised or it simply states that the video cannot be player. I can watch YouTube no problem. Please, I have tried and tried and tried to help myself before troubling experts on this forum. But can someone save my sanity? I am close to doing a factory reset and starting all over again with installing apps and the like. Aaaaaargh!!!
