Anyone own (or watched) the newest two disc release of Apollo 13? The one with the IMAX version included on the second disc. For those of you who do, can you tell me if they changed or improved the picture or sound quality? I am asking because the original release of the DVD I have is great in picture and sound quality but the bass is a little light during launch sequence. In fact, its down right wimpy. I expected the launch to rattle the windows via my sub as if my house was built right next to the launch pad at Cape Canaveral. I know that when a movie is released on DVD or re-released back into theatres there is often times little improvements done here and there to clean them up (dust specks) or add surround sound to old films etc. All in all I was just wondering what 'improvements', if any, they might have made to this DVD over the last one.
