What is a VOB file?
VOB (Video Object) is the primary data format on DVD-Video discs, stored in the VIDEO_TS directory. Each VOB file contains multiplexed video, audio, subtitles, and navigation data. VOB files use the MPEG-2 Program Stream container with specific DVD extensions for menus and multi-angle support.
How to open VOB files
- VLC Media Player (Windows, macOS, Linux) — Free, handles DVD navigation
- Windows Media Player (Windows) — With DVD codec
- MPV (Windows, macOS, Linux) — Lightweight
- HandBrake — Convert VOB to modern formats
