DVD VOB files store MPEG-2 video with AC3/DTS audio, subtitles, and navigation in a program stream container. MKV (Matroska Video) is an open-source container that can hold any codec combination with unlimited tracks, chapter markers, attachments, and metadata. MKV is the standard container for digital DVD rips in media server ecosystems.
MKV preserves everything from a DVD rip — video, all audio tracks, all subtitle streams, chapter markers — in a single file that Plex, Kodi, Jellyfin, and Emby handle natively. Unlike VOB's split-file structure (multiple VOBs per title), MKV combines everything into one organized file.
MKV also supports re-encoding the MPEG-2 video to H.264 or H.265 for dramatically reduced file size while keeping multiple audio and subtitle tracks.
FFmpeg or MKVToolNix reads the VOB program stream, extracts all elementary streams, deinterlaces the MPEG-2 video, and muxes everything into MKV's EBML container. For remuxing, the MPEG-2 stream is placed in MKV without re-encoding. For transcoding, H.264 or H.265 replaces MPEG-2 at dramatically lower bitrates. Multiple audio tracks (different languages) and subtitle streams (DVD bitmap subtitles as VobSub or converted to SRT) are preserved.
Remuxing MPEG-2 to MKV is lossless — identical quality. Transcoding to H.264 at CRF 20 produces visually equivalent or better quality at 50-70% smaller file size than MPEG-2. H.265 saves even more space.
