Computer as video source

Thanks for all the help on the auto-stop function, it worked!

Now for my next question:  Is there any way to pull the video from the computer as the video source.  What I am looking to do is to capture a PowerPoint presentation with audio (speaker talking) from the room it is being presented in (audio will not be an issue as we already have the capability), rather than video from the room.  Is there any way to do this without any cabling loops?

Thanks,

Mike
