Topic: Two playback screen issue

Hi All!

Unfortunatly i have a problem with the two playback screen.
If i put two video, than, i try to start (together or separate) then it just start for few milisecond and goes back to the begining of the video and repaeting untill i pause the whole video. What could be the problem? Any idea?
The videos are working well in single playback option.
