I had a 50" rear projection LCD TV on a dedicated stand between my speakers and had the same concerns. See the thread here. The perceived problems I had were minimized depth of soundstage, sound clarity, and visually having a huge obstruction directly in front of my line of sight that psychologically added to the decreased illusion of depth.
i have since removed it and replaced it with a wall-mounted plasma. All of the above issues have been eliminated or improved significantly
