please use eac3to to extract the audio and subtitles.

 

Below is the correct, minimal-nonsense way to demux every audio and subtitle track from that MPLS with eac3to. I’ll give you both the explicit per-track commands and a one-shot batch approach. This is the proper way to do it—no guesswork, no fluff.

---

1. Determine track numbers (already listed)

You have:

1: Chapters
2: Video
3: TrueHD/Atmos English
4: AC3 2.0 English
5: E-AC3 French
6: E-AC3 Spanish
7: E-AC3 Japanese
8–11: PGS subtitles (Eng/Fre/Spa/Jpn)

---

2. Extract all audio tracks individually

Use explicit track → file mapping. eac3to respects your extensions; use the correct ones:

eac3to 00800.mpls 3: audio_eng_atmos.thd+ac3
eac3to 00800.mpls 4: audio_eng_ac3_2.0.ac3
eac3to 00800.mpls 5: audio_fre_eac3.eac3
eac3to 00800.mpls 6: audio_spa_eac3.eac3
eac3to 00800.mpls 7: audio_jpn_eac3.eac3

Notes (technical, because you need precision):

• TrueHD/Atmos must be saved as .thd+ac3, not some improvised container.

• E-AC3 always uses .eac3, not .ac3.

• eac3to outputs the embedded AC-3 core automatically inside the .thd+ac3 file.

3. Extract all subtitle tracks

PGS subtitles are bitmaps → always .sup.

eac3to 00800.mpls 8: subs_eng.sup
eac3to 00800.mpls 9: subs_fre.sup
eac3to 00800.mpls 10: subs_spa.sup
eac3to 00800.mpls 11: subs_jpn.sup

---

4. If you want everything in one sweep

eac3to allows you to stack arguments:

eac3to 00800.mpls ^
  3: audio_eng_atmos.thd+ac3 ^
  4: audio_eng_ac3_2.0.ac3 ^
  5: audio_fre_eac3.eac3 ^
  6: audio_spa_eac3.eac3 ^
  7: audio_jpn_eac3.eac3 ^
  8: subs_eng.sup ^
  9: subs_fre.sup ^
  10: subs_spa.sup ^
  11: subs_jpn.sup

This is the sane, deterministic way to demux a UHD playlist—no shortcuts, no “auto” commands that silently produce junk.

---

If you want, I can also write:

• a full Windows batch script that auto-names files using language codes,

• or a PowerShell wrapper that parses the track list and demuxes everything automatically.

Just say the word.
