Well yes, You could Make one audio File the Left Channel and the Other the Right Channel and one audio file will Play out one Speaker and the other out the other speaker.... If you are Trying to make a DVD with 2 audio streams why not just make a DVD with 2 seperate audio Streams that you can select with your Remote controll???
Well i combined 2 video files into 1 and i extracted the audio files because i wanted to convert it two A3e DOlby Digital.....SO when i was done i wanted to know how to make them join together and put them back in the video
Well your DVD authoring program should do that For you...Any DVD authoring program worth useing will accept seperate audio and Video files and Many Prefer Seperate audio and Video files Like DVDlab and even Tmpgenc DVD author....
