I have a disk full of recordings from a Humax Foxsat HDR. They're .ts files with the AD audio track somehow set as the default (so if I play the files back on another machine I hear the AD track instead of the "normal" audio track. Could anyone tell me what TSMuxer command line parameters I would need to strip out the AD track from all of these files (or at least to make the AC3 track the primary audio track?).
