Hi I just purchased Apollo 13 IMAX version I played it on my computer (3ghz- 1.25GB ram- 4x dvd drive)figured the puter is fast enough. I had a problem with it running at a slow speed even the voices were in slow motion, I am currently using my puter temporarily as my HT is still under construction. I play all my other movies and they work perfect. Is there something I am missing with the IMAX version and why it plays in slow motion on the puter?? I will try on a real DVD player tomorrow but I would like to know if anybody else has this problem THNX!
