Problem Playing MP4 from SD Card

[abgninja]

Hello all. I come to these sites to get some help but all they do is talk in conflicting tongues.
I had the same problems of not being able to play mp4 movies from my sd card. It turns out that al sites were giving me rubbish.
The problem stemmed from fact that I was using a 64gb card which according to Samsung is acceptable. I could not play movies with no player on earth.
After a week of messing about work tablet, settings, formatting, I decided to try a smaller sd card namely a 32gb card. Behold a miracle, my problem was cured. Mp4 movies would play with the stock tab 3 player.

stock tab 3 player - where can i get it? I'm using Galaxy Tab 2 10.1
