Okay, so I finally have a little chance to catch my breath and I thought I would update with some details that I hinted at earlier:
I mentioned earlier that I had a minor issue with the screen I bought from Jamestown Home Theater. Here's what it was: The frame of the screen is made up of 6 boards; two on the bottom, two on the top and one on each side. These get fastened to eachother via a metal frame screwed to the backs of the velvet covered wood boards. Well, the two boards on the bottom arent completely co-planar. Its really not a big deal, but initially I thought it was responsible for a slight distortion of my image on screen. Turns out that was *my* fault - my projector was aimed at a slight angle and with the yaw adjustment I made it looked like only a part of the screen was "off" but it turns out that for the most part the screen is just fine. The slight amount of misalignment in the bottom two boards might be easily fixable by disassembling and reassembling but its frankly so minor that I dont feel like doing it. The screen is an excellent bargain - well constructed and easy to tension and I wouldn't hesitate recommending it to someone. And James at JTHT was very responsive and concerned. He definitely wanted to "make it right" if there was a problem with the screen. The screen I bought from him was an AT screen using Seymour Centerstage XD material. Woah! Its really nice. I love having the speakers behind the screen. I personally cant tell a difference in the sound of the speakers.
