QUICK ANSWER
Is it possible to convert BUP to MP3?
No - not a direct conversion.

A .bup stores DVD menu and chapter structure, not audio. To extract audio from a DVD backup, use HandBrake on the full VIDEO_TS folder - the audio lives in the .vob files, not in the .bup.

Why convert BUP to MP3?

The 1996 DVD-Video specification divides disc content so that .vob files hold video and audio streams while .ifo and .bup files hold only navigation tables such as chapter pointers and title lists. Since no audio data exists inside a .bup, there is nothing for any tool to decode into an audio stream. Any tool claiming to convert .bup to .mp3 is misidentifying the file or operating on something else.

How to convert BUP to MP3

HandBrake FREE

Open the VIDEO_TS folder in HandBrake and encode to MP4; HandBrake pulls audio from the .vob files and reads .ifo/.bup only for chapter structure.

MakeMKV FREE

Open the VIDEO_TS folder in MakeMKV to create an MKV from the disc, then extract the audio track from that MKV using VLC - MakeMKV pulls content from the .vob files, not from the .bup.

Quality & what to watch

  • The audio you hear when watching a DVD lives in the .vob files, not in the .bup or .ifo files.
  • Without the .vob files present, no audio can be produced from a DVD backup regardless of which tool you use.
  • HandBrake reads the .ifo or .bup for chapter and title structure but pulls all actual audio and video from the .vob files.

Frequently asked questions

I have only a BUP file - can I recover audio from it?
No - the audio was never stored in the .bup; it exists only in the .vob files. Without those files, the audio data is gone.
Can I rename a `.bup` to `.mp3`?
No - the file contains binary DVD navigation tables with a DVDVIDEO-VMG/VTS header; renaming does not change its contents, and an audio player will reject it.
What do I open to get audio from my DVD backup?
Open the entire VIDEO_TS folder in HandBrake - the folder must contain the .vob files, which hold the audio streams.
