I have a movie on DVD that is in PAL format, and the soundtrack is in German. I also have the same movie on DVD in NTSC format, with an english soundtrack. The PAL version has a much, much better picture than the NTSC version, so I'm wondering if there's some way I can combine the PAL picture with the NTSC soundtrack? There's a difference in the running time of each, so I'm not sure which is the best way to do this. I know I can demux the DVDs of each version, but is there a way to convert the soundtrack from NTSC to PAL? I want to preserve the picture as best as I can.
