After many rainy weekends and other commitments, I was finally able to enjoy an outdoor movie. I bought the projector and all the materials months ago, and planned for a 1 1/2" PVC "tlogan-style" frame. I cut the bottoms of the support pipes into shapes like pen caps, so that I could pound them into the ground. The screen itself is two pieces of blackout cloth joined in the back with duct tape. They sell blackout cloth in sections of 4 1/2', so I bought two 18' pieces for a 16'x9' screen (one foot on either side to attach to PVC). Unfortunately, I couldn't make this set up work. It looked good on paper but I couldn't get the parts into position by myself (might have worked with another guy or two). I even ended up snapping my PVC "pen caps".
On to plan B. Since my back yard is surrounded by a chain-link fence, I simply tied the PVC to two of the supports. They were only 15' apart, so I had some sagging, but you couldn't really tell once it got dark and the projector was blasting. I cranked up my Sharp XR-10X from Eco-Quiet mode (1750 lum) to Bright mode (2000 lum) and we didn't need to wait for total darkness.
In addition to the projector, my set-up consists of an X-box and an old stereo. I might upgrade to home-theater sound later. I hadn't given much thought to what movie to watch. The Polar Express had arrived in the mail (Blockbuster online) earlier that day, I selected it because my two-year old son loves trains. It turned out to be a great choice because of the superb animation and all the exciting movement. Almost "imax" like on the big screen at times; probably much less impressive on a TV. I highly recommend this film for outdoor viewing, especially given that we are all generally limited to "family" movies.
Thanks to everyone for your input on this forum, extremely useful info here. Now that I know everything works, I'm going to plan a get-together with friends, make a big deal about it.
