Overlay-Mode is a picture-in-picture feature that allows you to watch Zattoo while using other windows.
How Overlay mode works:
Overlay-Mode shrinks the Zattoo video into a small player that you can move around your screen and position over other windows. Clicking in another window does not move the Overlay window to the background > The Zattoo window in Overlay mode remains in front. The size is not adjustable as this is a requirement of Windows. To end Overlay-Mode, click "X".
How to activate Overlay mode in the player:
Click on the Overlay mode icon > The player opens in a separate window and can be moved to any position on your screen.
You can use Cinema mode as an alternative to Overlay mode. The Cinema mode allows you to adjust the size of the player individually. In Cinema mode, the player disappears into the background by clicking on another application. Read more about Cinema Mode here.
