Make sure the egreat reads native 10 bits! I could not find d that info as i did not look actually...
one of the video file, I could not play without any problem, is (Samson_and_Delilah_1949_DUBBED_1080p_x265_BrRip_30nama_30NAMA). I downloud it from internet, I think you can get it very easy if you search in google.
probably a SOC related issue @Dennis might help here and tell you if the chip can read 1080p 10 bit files
there you have your answer ! just sell that old model and get the A5, it is so much better and will receive updates until 2018
