So I'm one of those that are tired of buying the same dvd more than once. I saw that as a bonus feature Superman Returns will have the 480i version as well. Which for those who dont know means I can watch it on my standard tv with my standard dvd player. My question: does anyone know if I can use the Dolby TrueHD 5.1 surround track on my dvd player (which supports dolby digital and dts through my optical cable)? Or if I could extract the audio somehow from the hd version and sync it with my own standard version by re-authoring?
