I have some mpg files that have two different audio channels so basically the left speaker has one sound and the right speaker has a different one. How do I burn it onto a watchable DVD and still be able to choose between hearing one of the two channels? I've tried burning it with NeroVision but the burning process ends up combining the two channels into one so in the DVD player I cannot choose which audio channel to hear. I've been looking everywhere for a solution, I'm not sure how to burn it so it keeps both of the audio channels. Any help?
