Hi richard plumb,
My main concern was the ability to "service" or replace the screen without ripping apart the ceiling, or having to lift (as you pointed out) almost an entire bedroom floor. However, and just to warn you, I'll point out straight away that I think fitting from below is more awkward than tearing apart the floor above and dropping the screen into position.
As asked, here's the method I used:
Firstly, I still had to lift two boards next to each other in the bedroom, as I was adjusting the lighting circuit in the room below and also needed to run an HDMI cable to the projector at the back of the room.
With the two boards up, there was just about enough room to poke a torch and my head into the void to look along the length of the ceiling space between the joists to ensure no obstacles would get in the way of the screen (cables, heating pipes, noggins etc). Once satisfied that the space was clear, I drilled two small holes from the bedroom through the plasterboard into the room below to mark out the approximate position of the joists. This seemed easier than measuring the joist positions from the back wall and transferring the measurements downstairs.
With the two holes acting as a guide, I used them to mark out the opening to be cut in the plasterboard. I already had the dimensions of the screen, so I cut the hole just wide enough for the screen to be pushed up through the opening and long enough so that the screen would drop (stating the obvious!!) but still obscuring the ends of the projector casing. The hole was roughly 9.5cm x 200cm. The cuts were made with an old hand saw cutting about a foot out at a time to stop any bending or breakage of the edges.
At this stage it looked like this:
After getting the ceiling skimmed, it was then time to fit the screen.
At this stage ask someone to help you set the end stops on the screen, which are basically the screws that set the maximum up and down positions. Again, I knew the drop I needed, so we held the screen in the air and adjusted the screws until it stopped at the desired position. This saves having to keep taking the screen in and out of the ceiling to adjust the drop.
I then marked in the ceiling void where the screen fixings would need to go and then tried to screw in the fixings. Lots of twisted arms, dropped tools and swearing, but I finally had the screen in the hole.
The screen I bought uses eyelets that means it easy to hook up and take down. Also means you can level the screen, by adjusting the hooks.
After sorting out the electric cable, the only job left was to tidy up the edges of the opening by using some thin L shaped beading from one of the DIY stores. I mitred the corners to keep it as neat as I could and fixed it to the ceiling with the smallest amount of caulk.
Here's a close up of the end showing the trim:
Hope that answers your questions!
