The titleID-low for DLC is: ((uniqueID<<8) | DLC_title_index). DLC_title_index starts at zero. Each DLC item is grouped under a DLC_title_index. Usually an application only has one DLC_title_index, but for applications which have a *lot* of DLC there's more than one DLC_title_index(JPN Home Menu for themes for example).
