is there an undocumented reset pvr database function?

I know there is a builtin function to start - restart pvr manager (StartPVRManager) but just wondering if there is an undocumented builtin function to reset the pvr database.

I'd like to reset the pvr database by adding a button within a skin I am designing for example. I want to make it easier to reset the database without having to go to LiveTV settings menu.

Does anyone have any suggestions?
