As in computers, not "politically correct." The result is Mac users are at a disadvantage when viewing this site. All new videos will be in .wmv format, which is a Windows file type less than 1/3 the size of the .mpg files Mac users can watch. Where PC users will see videos, Mac users will see white space. Unless you can figure out a way to force Apple to allow you to watch Windows files, you'll have to use a PC to watch new videos. You can still watch the .mpg videos of course.
