I've had my 16GB A500 (3.2 original firmware) for a few days now and im overall impressed with it apart from the fact i can't get video to playback smoothly on it. I've installed Moboplayer with the correct codec pack and the 720p mkv file i first tried to play had very stuttery picture and sound so i started looking through the forums and found that mkv's don't play well and that i should try avi format instead. I tried a 720p avi file and it still had the stuttering issue so finally tried a DVDrip avi and although it was better, the playback still wasn't smooth. Am i missing something or is this tablet just no good at playing back video? I've looked around on the net and loads of people seem to be able to playback 720p with no problems so what am i missing? am i just using the wrong player or are there some settings that can be optimised? Any help would be much appreciated.
