We're trying to record the desktops of users using demo versions of our software (this is an in-house lab setup). We need to have the recording happen on a separate computer (just across the room), so that the recording software doesn't interfere with the user.

Every screen recording software I've seen will only record what's happening on the computer its installed on; ie, you can't record what's happening on another computer. So it seems I need to cobble together a solution (unless anyone knows of software that will do this).

Getting the video to the other computer seems easy enough. I'm using TightVNC with the DFMirage driver on the test computer. The recording computer connects to the test computer with TightVNC and then uses CamStudio to record what's happening.

The real problem is how to deal with the audio. We need to record both what the user is saying (through a headset mic) as well as the sounds produced by the test computer. But VNC doesn't transmit audio. :(

I'm not sure how to get both audio streams (mic and sounds) over to the recording computer. Any ideas?
