Sorry, gang, I know it's been a while since I've been able to get back to everyone on this subject, but I've been swamped.
Here's what I've learned so far...
The out board processors that these exotic projector companies are selling are, in fact, re-cased DVDO pieces that have slight software tweaks. These "tweaks" are done mostly, according to my guy @ DVDO, to the menus. Meaning: The graphics of the menus are different. Bottom line: Core performance & feature sets are identical when they leave the factory. The add on processors from a few of these companies that I mentioned earlier retail @ roughly $1K or slightly more over the equivalent DVDO processor. I do not think this is true regarding Meridian's processor. I believe that to be an in-house piece and not outsourced.
But, it isn’t all bad. These re-badged processors have more inputs than the DVDO counterpart and one company claimed (and I believe them) that while DVDO does ship them the core piece, they (meaning DVDO) have no control over or ideas as to what changes the projector company themselves make to the software. What are these changes exactly? More & refined adjustments making it easier to get an exact ISF calibration, more control options, more accessories to enhance performance (however so slight). "Value", I don't know. Different? Slightly. Please read on....
While, yes, these projectors are all based off of the JVC RS1 & RS2 platforms they are (slightly) modified from the originals. Example: quieter fan, easier calibration tools, accessories (like lenses or 2:35 sleds) are more plentiful, etc. One of these manufacturers gave the following analogy: They're like a professional car tuner. They buy the Corvette, make adjustments to squeeze out every last drop of performance, and then resell it. When I asked the rep of one of these brands if he'd ever done a side by side comparison of his model & the RS2 it was patterned after I got a "No", which I found incredibly disappointing. They are wanting to reach a market segment that's not interested in comparing for value (and yes, there are a great many of those people out there) and is only interested in the "best" performance regardless if it's only better slightly or just in theory, on paper, or more expensive.
Before anyone starts to get really worked up I just wanted to point out that not too long ago, Runco used to buy Zenith CRT projectors that retailed @ $12K & essentially re-badge & re-case them as "Runco" and then sell them for $20K+. Nobody complained a bit.
I hope this helps....
