samsung tablet will not play movies I added to SD card

I have copied movies to my sd card on my Samsung tablet 2 10.1. they work fine on my computer and on my tablet, suddenly the last four movies I sent to my tablet will not play the movies, it shows no data and says it can not play video file. I put all of my movies on the sd card so it is not a storage issue, I have plenty of storage left. I don't understand why its not working, I even downloaded another video player and no luck. Can someone help
