say i want to get the speaker audio stream and record it to wave, how do i do this.
I want to make a screen recorder with sound activated, I guess getting the windows screen into a bmp file is a windows command, is this possible this way also?

you used to be able to fit a game on a disk, then you used to be able to fit a game on a cd, then you used to be able to fit a game on a dvd, now you can barely fit one on your harddrive.

I am going to assume on Windows only?
Well, there are two orthogonal issues: one is Vista vs. earlier OSes, and the other is DRM vs. non-DRM audio.
For example, on Vista or higher, look into WASAPI (Windows Audio Session API) in CoreAudio. YOu can easily jack in and do some loopback recording. However, it won't work with DRMed audio.
On earlier versions of Windows, or with DRMed audio, you have to get much more exotic. You basically have to build a driver (a filter driver, I think). Not a quickie type task, that's certain.

Hyperbole is, like, the absolute best, most wonderful thing ever! However, you'd be an idiot to not think dogmatism is always bad.
