ProgramInfo * LiveTVChain::GetSwitchProgram	(	bool &	discont,
		bool &	newtype,
		int &	newid
	)

Returns the recording we should switch to.

This returns a ProgramInfo* and tells us if this is a discontiuous switch and whether the recording type is changing.

This also clears the NeedsToSwitch()/NeedsToJump() state.

NOTE: The caller is resposible for deleting the ProgramInfo
