During conversion the Convert object checks whether the ltmmSupportManager object is loaded and whether the DVD conversion capability is unlocked. 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.

The user must unlock support for a specific feature before using that feature. The Key must be obtained from LEAD. Contact sales@leadtools.com.
