Member	Description
Application	Unlocks the module for this instance of the application. This is the recommended value.
ApplicationPath	Unlocks the module for this particular application. Use this for unlocking support in a third party application (like Windows Media Player).
Computer	Unlocks the module at the computer level. Unlocking at the computer level should be avoided because it can cause unexpected behavior in other applications.

The MultimediaSupport.UnlockModule and MultimediaSupport.LockModules methods use a parameter of this type to indicate how to unlock or lock multimedia features.
