Hello, I recently purchased an Acer Iconia a500 tablet and I have problems playing MP4 video files (HD 720p ones). I don't know but for some reasons the movies are played much faster than normal. When I use Moboplayer, the files are played like 8x faster than normal and there's no sound. And I have absolutely no control over it. I tried Dice player and it's a little bit better. It only seems to be played 2x faster but no sound either. I read AVI files ok. Moboplayer was able to play an MKV file but it wasn't great. It was choppy and there was no sound. *Sigh* VLC media player just can't come up with their Android app soon enough... Anyway, can anyone help me or at least explain to me what's going on?
