View Full Version : Audio Oddity In MuxMan

I am re-authoring a dvd in MuxMan v0.15R that has two audio tracks.

Audio Track #1 is main movie's original Japanese 5.1 AC3.

Audio Track #2 is English alternative director commentary 2.0 AC3.

Even though I'm putting the JAP 5.1 AC3 as Track #1, after authoring the dvd it's playing the DC 2.0 AC3 as default track.

Why is this happening, and how can I fix it?

Here's the log from MuxMan:

Maybe it's because your player is configured to play English by default.
You can force a specific track with a SetSTN command.

I believe you were right! I was testing playback via MPC and it was defaulting to the English track. I played the same newly authored dvd in VLC and it played the proper Japanese audio track.

Does this only happen with software players? Or can USA standalones also be pre-configured to choose English tracks first regardless of order?

Where in the .mxp file in MuxMan can I force the Japanese track to be played? Would it be just below my other SetSTN command to auto-start the English subs?

All players should have a setting menu to select the preferred menu, audio and subpic languages.

Yes, you can force the audio track the same way than the subpic.
However, note that the same audio (and subpic) will be automatically forced each time you play the title, regardless of the change the user has made previously, either directly with the remote or via the language menu of the DVD.

So even after the movie is playing, by using that SetSTN command to force the Japanese audio track, I won't be able to switch it over to the English commentary using the dvd remote?

Yes, you can change the audio and subpic tracks during the playback of the title. But if you play the title from the beginning again, your old choice will be lost, as the SetSTN command, executed just before the beginning of the playback, will be executed again.

Gotcha! What is the syntax for forcing an audio track using an SetSTN command btw? SetSTN audiotrack=1:ON ?

Yes, or something like that. (Honestly, I don't use Muxman to define the commands. I prefer PgcEdit!) ;)
Anyway, you dn't need the "ON" flag, as an audio track is always on.
And don't forget that the tracks are numbered from 0, so the first track is track #0.
So, I guess the correct suntax is simply:
SetSTN audiotrack=0

Sorry, I have verified with the GUI, and Muxman uses a 1 based numbering, and "audio" instead of "audiotrack". The correct syntax is therefore:
SetSTN audio=1

Thanks r0lZ!! That worked out perfectly.
