Here are some of the programs that I use:

Screen Capture:
Sigis Screen Capturer

Audio-Video:
VLC - Video Lan Client
WinAmp

VLC is like the swiss army knife of media players. It will play almost anything. The deciding factor of VLC being my favorite client would be the ability to stream the media. I can stream media using vlc to any other computer in my house.

Games:
America's Army
When time and family permits this is where you will find me. Online trying not to be called a NOOB.
