Notes :

- Timer slider mod
Enabling only the "Time Slider mod" doesn't seem to work.
But, I noticed that if you enable it and check the box named "Update file servers" and save and after that you go to the "servers" section and click on your server and that you click save, the Time Slimer mod will take effect and will work for the future videos.
for the videos uploaded previously, you must go to the section "videos", select the videos and click on "Extra functions..." and "Regen thumbnail"
