Flask / Graphedit / Ac3dec / SmartRipper etc., only give me one language or no sound option at all?
With Flask you can try increasing the search size in the audio settings. But if, for some reason, one or all of these programs cannot find a secondary audio track, you will need to get the AC3 files yourself. To extract any AC3 file you can use VStrip or Vobsnoopy, then listen to the AC3 files to see which one is the language you want. Merge them together with FileMerger and encode to wave or PCM with any method you like best.
