There's a whole host of freebie screen capture softwares that will allow you to capture specific programs and claim that they will allow you to choose the audio source.

I was unable to make this work with any of the following on my system, but all were recommended to me as being capable.

YouCam
Camtasia
CamStudio

I think the issue is that right now, I have to run my 32 bit DAW software as administrator, and the screen capture software was running native 64 bit on my Win7 Home Premium 64 system. None of the folks recommending these programs had that hoop to jump through.

I do think that Mac's answer is probably where you will see/hear the most joy. The problem arises from the fact that web cams also usually are USB 2.0 devices, and a high quality video data stream may not be even possible over USB.
