Thanks for the kind words, I am glad the DTS-10 worked out after all, it is probably overkill, I am never going to be able to utilize more than 25% of it's potential, I'm baffled by the guys on this board that have more than one of them in their rooms.
I got another velvet wrapped front frame done yesterday, now the top, bottom and right side of the screen are done, once I get the left panel built I can move on to the columns.
The projector is sitting on top of a stack of boxes and I have been using my htpc as a source for some testing. The htpc has all of my blurays ripped to it using makemkv. I have it zoomed out so that 2.35:1 material fills the screen and 1.78:1, 1.85:1, 4:3 material etc, all spill over the top and the bottom onto the black velvet masking.
My plan was to set the permanent resolution on the htpc to 1920x800 or 1920x817, not have it zoomed, and then I thought the scope movies would fill the whole panel and match the screen, and smaller aspect ratio movies would get shrunk down by the htpc and fit the screen. I'd lose some resolution on the smaller aspect ratio shows, but it should be good enough for now until I upgrade to a projector that does auto-zoom.
I tried setting it up that way and it worked perfectly for the 1.85:1, 1.78:1 shows, but all of the 2.35:1 were being shrunk and displayed with black bars on all sides. It was hard to figure out what was going on, there isn't a lot of info out there about this kind of thing, I guess the market is small for constant image height using an older projector and people who want to use their pc to shrink their source material. What I think is going on is that the blurays I transferred to the htpc, the black bars on the top nad bottom are actual black images that are included in the source. I'm going to try and use handbrake to re-encode the images while cropping out the black bars, then project them and hopefully the image fills the screen.
