Windows media player To enable landscape mode and avoid the screen display rotating when you select "full screen" display on you have to add a registry key to the S620 registry.

The key to be added is

HKLM\System\GDI\Rotation\LandscapeMode=0

This can be done by downloading the Total Commander Program CAB file at

http://ghisler.fileburst.com/ce/tcmdphone.cab

This needs to be copied to the phone using ActiveSync.

Execute the CAB file and the program installs.

Select the registry editor plugin and navigate to HKLM\System\GDI\
Create a new folder called Rotation
Navigate to the folder and add a DWORD called LandscapeMode
Set the value to 0.

Thats it. After that whenever you select "full screen" from media player the screen will display in the landscape mode and use the full screen, and not rotate around, losing most of the viewing area.
