I'm pretty new to OSX, I'm a switcher as of last week, but I was pretty techsavvy before that on Windows. My question is about loading video files, When I doubleclick on a movie which is an AVI, I get the beachball for almost a full minute. Because this is a week old 2.4ghz dualcore machine, I expected movies to open faster than they do on my windows box which is a 2.0ghz singlecore. I'm convinced there is something wrong with my setup, maybe a codec problem, but I dont really understand how Quicktime works. Is there a codec pack I need, or something? As a second and less important issue, I also cannot drag to import most of my video files into iTunes, only a few work, so I believe it is also a codec problem, that iTunes is not recognizing most of my videofiles (I dont mean WMV, I know better than that, these are all AVI and some work, some dont). I'd like to load up enough codecs to get this thing working properly, but don;t know where to look.
