It's really funny.
Deleted the %appdata%\VLC folder.
Starting a video now gives the correct size but no video. Only sound.
Changing Video Width and Video Height ór uncheck Disable Screensaver, shutting down and restarting VLC will give the 0 height-video again but with the resizing (manually see above) the video plays.
During all phases, it is not possible for me to change the Zoom Video setting
I belive that when settings are saved, this Zoom Video setting of 0 is saved so all video's are zoomed 0.
Should be able to change that.....but how ?
Thanks for the quick reply.
