VTS, which stands for Video Title Set, is a name given to video files that are present inside DVDs. These files use the .VOB file format and are encoded with the MPEG-2 standard. Windows Media Player 12, which comes built-in to Windows 7, provides native support for MPEG-2 encoded files so you can play any VTS files that you have without installing third-party codecs.
