Hi and thanks for answer!

First i have to say, i run a random playlist with about 200 videos! Most of the videos run correct, just a view of them run at wrong/to fast speed. My setting are the default/same like shown in your picture. One more thing i forgot to post, i use only clean videos without deskscapes package, and as i said, i tested the wrong speed videos on a normal video player and they run at correct speed.

hi, i checked this, but the file still run to fast, so i decided to go an easier way by converting the file to a other format (mp4 to h264HQ/mkv) the file now is 4 times bigger, but it runs perfect now... thanks anyway for your help!

One more question, i use some really nice clips as deskscapes, for example from the movie Bladerunner, which i would share with others here, but i'm not shure about legeal/licensing. If you like, i would send them to you for check them, and if you like share them here! The files are like most of my other dreams pure videofiles without Deskscape container... So if you are interested , tell me...

Marry Christmas
