The OtsAV window has three display mode settings: compact mode, normal mode, and extended mode.
To switch between the window modes click the 
icon on the toolbar.
Compact mode: This mode compacts OtsAV to a single deck, which can be placed any where on the Desktop. This mode is great for when you wish to have OtsAV playing in the background while you work with other applications, or if you are running multiple instances of OtsAV and want to see what is playing in each instance.
Normal mode: This is the default window mode, which is for 800 by 600 screen resolution. This mode can be used on the 1024 by 768 (or higher) screen resolution enabling you to easily access the Desktop behind the window.
Extended mode: This mode extends the OtsAV window to fill your entire screen, up to a resolution of 1600 by 1200.
Note: If you are using OtsAV on a system with the screen resolution of 640 by 480 you will not be able to view the Centre Panel feature. For this feature your display device must be able to be set up at 800 by 600 screen resolution or higher. To view the On-Screen Video Monitors when playing video or CD+G items, your resolution must be set to 1024x768 or higher.
