A couple of points to make...
For a start, there'd kind of be a legal issue with allowing qt to play propriotary format files (such as rm) with no permission with real. Secondly, Apple and MS aren't teaming up to crush real... from what i've heard, apple's got some sort of deal with real... And if those MPEGLA ppl weren't so f***ing greedy, we wouldn't even be discussing this issue -- I don't think we should support the wide use of .mov files any more than we should of .asf or .rm files. They're all propriatary and they all suck ass. Sure, I prefer QT, but you can't play .mov files in any other player apart from QT...
