IF0 / BUP
IFO/BUP discription
IFO files contain the formatting information of the VOB files, which tells the DVD player exactly how the DVD should be played (eg. aspect ratio, subtitles, languages, menus etc...). BUP files are backups for IFO files, which are needed if the IFO files gets corrupted. If you rip the DVD without IFO files, then the VOB files may not play correctly, or may not even play at all. Similarly for conversion, IFO files are essential since video converters like FlasKMPEG (which supports IFO parsing) will need them if you want to encode videos, or fix multi-angle ripping problems.
