Use the IltmmSupportManager::UnlockSupport function to unlock support for DVD conversion. Use the IltmmSupportManager::IsSupportLocked function to determine whether support for DVD conversion is unlocked. During conversion, the Convert object checks whether the ltmmSupportManager object is loaded and whether the DVD conversion capability is unlocked.
