What are .IFO, .VOB, and .AOB files? How can I play them?
The DVD-Video and DVD-Audio specifications define how audio and video data are stored in specialized files. The .IFO (and backup .BUP) files contain menus and other information about the video and audio. The .VOB files (for DVD-Video) and .AOB files (for DVD-Audio) are MPEG-2 program streams with additional packets containing navigation and search information. Since a .VOB file is just a specialized MPEG-2 file, most MPEG-2 decoders and players can play them. However, any special features such as angles or branching will cause strange effects. The best way to play a .VOB file is to use a DVD player application to play the entire volume (or to open the VIDEO_TS.IFO file), since this will make sure all the DVD-Video features are used properly. The DVD Video Recording format will introduce .SOB files

Many DVDs are encrypted, which means the .VOB files won’t play when copied to your hard drive. See 4.5. You may also run into .
