BUP, VOB and IFO are DVD files. Each format is a specific tool that DVDs use to play on a DVD player. BUP is a backup file. VOB is the main video, which is similar to MPEG. IFO files store information on the DVD like subtitles and sound. Converting DVD media to another format will allow you to change certain media applications. AVI is a standard video format. However, one AVI file can only hold 2 GB of data.
