Re: 1.78:1 vs. 1.85:1
I'm not sure exactly what your getting at, but in reality it probably doesn't matter a lot.
Almost all HDTV is/will be 1.78, most HT projectors are 1.78 so that would seem to be a down/dirty best answer if you are looking for a set that will be used primarily for TV viewing.
Even assuming you are interested in Movie Only, the true difference in the screen size for 1.78/1.85 is virtually nil. At a 50 inch screen height you are talking about 3.5 inches in width. From the typical/usual optimum viewing distance calculators, the Field of Vision difference will be almost indistinguishable. Translated an approximately 50 inch height screen is 102in diagonal for 1.78 and 104 inch at 1.85 looking at Carada's website.
If you decide have a letterbox/pillarbox presentation or eliminate 1/2-1 inch borders from the top/bottom or sides by using the zoom in/out on any 16:9 projector I think it's likely a wash in terms of picture quality. The choice of overscan variations among projectors likely would make a sinficantly bigger impact than the 1.78/1.85 decision.
If you decide to go to a constant height setup with a 2.35:1 ratio screen then it beomes much more of an issue. I personally find I notice the lateral dark borders much less watching 4:3 material on a 16:9 set than I noticed the top/bottom borders watching widescreen material on a 4.3 set and I am a pretty big OAR advocate so it never bothered me to watch letterbox material at all.

Re: 1.78:1 vs. 1.85:1
As noted very few films (DVD or Blu-Ray) are shot in 1.78:1 aspect ratio - so really 1.85:1 is defacto HDTV.
Personally - I want what the director and editor wanted. I don't care if that is 1:1 or 2.40:1 - I want to see what they created and what got all the fuss up at the theater.
For years I have bought nothing but widescreen additions (DVD). And when I see an 'upgrade' I replace DVD's as a can.
