Actually, it is a backup tool for your new created DVD. If you use "Burn DVD Folder" item, which can be found in the "Tool" menu, you will get two folders in the output directory you set, "Video_TS" and "Audio_TS". In the "Video_TS" folder, you will find VOB files, IFO files and BUP files, etc. They will form a standard DVD if you burn them into a DVD disk by any other burning program.
