Soundflower
On the iMac, at home, I use iShowU HD. Lovely tool for capturing anything that happens on the screen.
Out of the box it works nicely, but there one or two things you need to do to make it fully operative.
One is enabling access for assistive devices so you can record your keyboard strokes.
The other is installing Soundflower in order to record system audio. That is.., the audio created by any application on your screen.., not the microphone or the line-in.

This is where it went wrong on the Mac Pro at work. After selecting Applications settings for audio, iShowU wants you to install Soundflower. Now there should be a nice Kext in ../System/Library/Extensions/.
It did exist on my iMac, not so much on the Mac Pro.
So, I hit the fora and didn’t get to an answer quick enough, though I did see a suggestion to check my logs. In it I found the kext was missing.., so I searched for the kext.
I found an article by Jed Laundry about the soundflower.kext, but it was unrelated to iShowU. However, Jed was kind enough to put up a link to code.google.com where the Soundflower package is hosted.
So, if your run into an install error with iShowU and it complains about Soundflower. Chances are, the kext is not available. Downloading the DMG and running the PKG install will put the kext neatly in the Extensions folder.
iShowU should not have anything to complain after that.
