What is a VOB file?
VOB files store the video on a DVD, inside the VIDEO_TS folder. Each one holds MPEG-2 video with AC3 or MP2 sound and is limited to 1 GB, so a film is split across several VOB files. Home-made DVDs without copy protection can be converted; commercial DVDs are encrypted.
VOB is mainly used for home-made and camcorder DVDs. It plays on DVD players, VLC and DVD software.
