Video problem

[bongimdu]

Hello to all.

After image upgrade from 5.2.032 to 5.2.034 I lost possibility to watching video files .
I have plenty mp4 files with video music and movies which worked fine on 5.2.032 image.
The problem is when i play video file (mp4) I can hear only sound but no picture , whats more confusing i can see osd menu
and time elapsing etc. but no video from file just sound.

my current settings for video output is HDMI 1080p 50Hz
but noticed when change it to 1080i 50Hz video files playing without problem
as I said before upgrade to 5.2.034 everything was fine .

I enabled debug log with resolution set to 1080p 50Hz played video file ( no picture ) then changed resolution to 1080i 50Hz ( picture ok )
Can I ask You guys to have a look at it as I cant see any clues in it .
Thank You

Same files on TM nano se on latest 5.2.034 working ok no matter what resolution I set.
