Hello I bought a couple of months ago the box Ziddo X9 which is really great. But last week I installed a skin for ZDMC which did not work very well ... So I did a factory reset on the box and I re-installed my applications. Now I have a problem, when in ZDMC I put the function '' use an external player '' All my standard * .mkv files are no longer read. Only iso files work !! Can you help me In advance I thank you Mike P.S. I specify that before doing the reset the player extern read everything ...
