All, Thanks to all of you who contributed information and ideas before, during, and after the build out process. The media room itself is about 16 by 20. It's attached to a 10 by 10 game room that runs separate speakers / volume control off the receiver's powered second zone.
Here are some photos showing what I originally had to work with (a cut out space for a basement fireplace), and the media center I built to fit in this space. The equipment is pretty basic stuff - Onkyo 602 receiver, Onkyo 302 DVD, D*V HD/DVR, S*ny PS2 plus IP*D docking station. I included open shelves to handle DVD's (kind of like art work) plus additional storage in the cabinets below.
It took awhile to get it all done, but damn was it ever worth it!
Dang it...who here knows how the upload function is SUPPOSED to work? I've attached the four JPEG files and received a message back that indicated they should have been posted.
