Real Player really sucks
Excellent analysis of the obnoxiousness of RealOne's defaults, which hijack the hell out of your Windows box and install shortcuts everywhere imaginable and grab anything remotely AV and try to play it back in Real and spam you with upsell offers and other creepiness. I like MPlayer and VLC for playing back Real, WMV, and MPEG files, as well as DivXes and the like.
