Conference Room Theater  I would like to set up a conference
room with audio/video capabilities. I am planning to use a 7.1
A/V receiver for audio and InFocus 5124 LCD projector for video.
This would be used for training and presentations as well as

would be able to use the A/V system for a slide show from a
computer (potentially with a sound track) and talk over it with
