Would you upgrade a DVD if it was one of your favourite movies but you knew that you would not watch it very often. In fact, if you KNEW that you weren't going to watch it more than once every 3 or 4 years. Would you still bother upgrading, if you're going to watch it so far apart? If the movie itself looked hideous in the current version, I'm sure anyone would upgrade it, especially if it's one of their favourites. But how about if it looked "just ok" and not great? Would you still upgrade?
