A DVD contains many different types of files. These files include VOB, BUP and IFO files. The IFO files contain important information tracks and chapters, as well as aspect ratio information, which controls the size and dimensions of the picture. Many software programs can convert a DVD IFO file to an MP4, such as AVS Video Converter, DVD Ripper for Mac, and Daniusoft Best DVD Ripper. Warnings Writer Bio
