An EVO file (Enhanced VOB) is a container format contained in HD-DVD and Blu-Ray Disc video media. It contains the actual video, audio, subtitle and menu contents in stream form. EVO files can contain video encoded in H.264/MPEG-4 AVC, VC-1, or MPEG-2 and audio encoded in AC-3, E-AC-3, Dolby TrueHD, DTS, DTS-HD, PCM, and MPEG-2. There are currently only a few consumer software solutions that can play EVO files - PowerDVD, WinDVD for Windows and ffmpeg for Linux (unprotected EVO only).
