ReMOSD

ReMOSD is a small and simple program that allows you to hide multimedia OSD windows that appear on your computer screen. This can be useful if you want to get rid of the advertising windows that appear when playing video or music, or if you want to hide the player controls.

ReMOSD works by blocking all communication between the player and the OSD. This means that the OSD will not be able to be displayed at all, even if it is enabled in the player settings.

ReMOSD is very easy to use. Just download it and run it. The program will automatically run in the background and block all attempts to display the OSD.
