Default Can't play movies on my GT-I9300 device

Hello,

I am using MX player to play movies downloaded from torrents, but I am unable to see them as I get the error: Video problem - can't play this video. The file is ok without any problems, it runs very well on my desktop. For this moment I have two files with problems : 12.Years.a.Slave.2013.BDRip.Xvid.Rosubbed-LTRG and
12.Years.A.Slave.2013.BRRio.Vvid.AC3.RoSub-playXD
Both of them are with avi extension. I tried the same movie multiple times believing it's an encoding problem.

Do you have any ideea or I must configure something?
