I have numerous transport streams which contain both english and non-english audio, with the non-english playing by default from several streaming devices. I cannot find any way to change the audio stream on these devices.

Is there a way to change the default audio stream within the ts file without re-writing the entire file? Maybe just a flag or header change? I would like to avoid having to strip the non-english audio out of each movie. (That would take a lot of time and hundreds of gigabytes)

Thank you
