Since I see some comments about video playing, I'll throw in a pitch for VLC Media Player. It's free, available in 32-bit and 64-bit versions, runs under Windows, Linux, Mac, even has some obscure executables for formats like Sun, I think, and will play basically any format of movie out there, anywhere, with all sorts of options for display format, audio settings, subtitles, etc. +1 because it's what all the hackers and pirates on The Pirate Bay website use, so they're not likely to hack their own player, LOL.
PS - WinAmp blows, big-time. :p
