I kinda thought so...
I had a feeling that there might be some problem like that with the furniture and the dining room set-up, but I thought I'd just toss it out there. One of the things that's always impressed me about the home theater pros that I've talked to in my neighborhood (northern Detroit suburbs), is that most of them look at things differently than the standard, "I gotta have it this way," mind-set we, as home-owners bring to the party. Okay, that I bring to the party.
By looking at things differently, though, and proposing some "What if..." ideas, I think sometimes the creative gears can get churning.
Good luck with that room.
