From 5.0.013 i upgraded to 5.0.14 from decoder menu and after reboot i have no video on screen, only audio and epg works from iptv source and recorded movie.
Download and flash of 5.0.14 didn't solve the problem, then i flashed back to 5.0.013 and video is ok.
Re-upgrading from 5.0.013 to 5.0.14 broke video again.

Now i'm on 5.0.013.
