Public service advisory: if you have to use RealPlayer (or RealOne, or whatever they're calling it this week) and you're on Windows, you've probably noticed that it is loaded with spyware and annoying behavior. Thanks to a deal the BBC struck, they have a spyware and annoyance free version available for download here. Run, don't walk, if you need a copy.
UPDATE: Word from inside of Real is that this meme is bullshit...there's no difference between the BBC version and others. So I'd advise folks to simply avoid Real.
