I have version 1.9.14 installed on my Samsung Galaxy S7 with the lastest codec pack and i have not any problems.
So it must be on your device there is a problem.
So is this really the way things work with MX Player Pro from now on?
I must use custom codec to watch mpeg2 decoded videos and for every new update of MX Player I will need to get new custom codec?
I updated the MX Player Pro yesterday to 1.9.8...
Try version 188.8.131.52 https://drive.google.com/drive/folders/0B1cOHQ70J9vlUEpDX1ZlazdjMms
Or version 1.8.6 https://drive.google.com/drive/folders/0B1cOHQ70J9vld0lVRnZHczBkbTQ
