Anybody else have a problem playing back Superman Returns or Hulk on the PC? I am running AnyDVD HD 188.8.131.52 & PowerDVD Ultra 7.1 on Windows Vista Home Premium. 1. Superman Returns freezes when trying to play back the main movie files 2. Hulk starts with the Special Feature documentary, but I can play the files manually. Superman Returns played fine while I had Windows Media Center Edition 2005, but was a little choppy. Now, it doesn't play at all after upgrading to Vista.
