Your set up looks amazing. Are you sure you're not just making up problems for yourself so you have something to do?
I have one decent sized room as a finished basement and it has 4 pins and my "home theatre", which is basically an $300 720p HD projector shining about 60-70" on a blemished, white wall with no screen. Cheap Onkyo 5.1 home theatre speaker set up. And I think it's absolutely awesome.
I'm positive that you guys with the real deal sets ups are getting a "better than going to the movies" experience, but since I don't know what I'm missing, I'm perfectly happy with what I have. I watch movies and kids love playing their wii down there, etc. Wish I could fit more pins, of course, but I "only" have 4. If I had 8 I'd feel more than satisfied.
