[dvd::rip] missing ' ifo' file

Hi there list!

After following dvd::rip guide on the official page, when I check the layout of my directories I can't find any IFO file in spite of vts_01_0.ifo into /temp/. Have I made any mistake during the trancode process or the ripping process?

~/dvdrip-data $ ls -XRh1
