RBE has very little to do with motion. RBE effects mostly occur under two scenarios.
1.) The scene or shot is a "high contrast" one. This usually means things like whites on blacks. Examples would be when credits are rolling, a black and white movie or scene, star field shots.
2.) Brightness is the major reason why people see rainbows. The brighter the projector the more of a chance you're going to see separation artifacts. High brightness combined with a slower color wheel, or one that has less than 5 segments is usually RBE city. This is partly what I was talking about before about higher end DLPs. What you get typically is a 6 speed, 6 or 7 segment color wheel with the higher end models. You also get other cool things with the more expensive models like lamp modulation technologies. Osram's Unishape lamp technology has done wonders for the DLP world. You get better contrast and less RBE artifacts with the technology. Most of them are also not light cannons which is why you don't typically see a lot of complaints about higher end DLPs and RBE.
I just recently sold a JVC DLA-X3, a very current model, and motion is still a very big issue in my opinion and you'll see a lot of users on here who are on the same page as I am. I think it's one of the last major hurdles JVC needs to get over to give a practically flawless overall PQ package. Sony used to be on par with JVC in regards with motion and they have since did a complete overhaul to their LCOS chip and motion is no longer an issue for all but the pickiest. You may be one of the lucky ones who don't see the motion issues and I envy you. It's one of the only reasons I couldn't own a JVC. I won't be purchasing another unless they fix the issue like Sony did.

I'm replying from work so don't have exact measurements but again this sounds very similar to my set up. I am using a 120" 2.35:1 screen, My basement has 9' ceilings and my JVC is mounted approximately 14' 9" from the screen and on a "low profile" mount that provides only about 4-5" of clearance between the projector and the ceiling. There is a single bulkhead on the ceiling about 3.5' in front of the screen which extends down about 10". My screen is mounted perhaps a little higher than it should be for optimal eye level viewing when seated on the couch (roughly 4.5' from floor to center of screen) but low enough to provide clearance for the projected image to clear the bulkhead. I believe the bottom of my screen is around 30 inches from the floor. When viewing regular 16:9 content the image clears the bulkhead above and there seems to be plenty of room to still shift the image down. How far I'm not completely sure. I use the zoom memory feature when watching 2.35 content and when doing part of the actual 16:9 image is projected onto the bulkhead (about 3" worth). Thanks to the great blacks of the X30 this can never be seen unless you flip to a 16:9 image while zoomed out (or in stupid dual format movies like Dark Knight).
For your exact set up you could probably make use of coderguy's excellent site; http://www.eliteprojectorcalculator.com/
I don't have, nor have sufficient experience even viewing, an anamorphic lens so I can't comment with any authority on the pros and cons. I can say that I would consider myself pretty discriminating though and I have no desire to acquire a lens for my set up. Thanks to the pixel density of the JVC LCOS panels I can get right up to the screen even when zoomed to the full 120" 2.35 image and have no issues with image quality. Technically you will get higher horizontal pixel density with an anamorphic lens but unless you pony up for very high quality optics it's apt to get lost in lower brightness or other lens distortions. I have seen many people on this board report that they use the "zoom method" to watch wide screen content with their X30's and I can't recall many expressing that they felt they HAD to get a lens. In fact it often seems to go the other way. Those that have a lens sometimes decide to sell it off after realizing the zoom method is pretty good on it's own.

I'm not saying there will be zero separation artifacts, but they become reduced to an amount that is very small. I also on occasion see them. They just don't bother me like they do some people. The effect isn't a constant one that you will continue to see no matter the content like motion issues are. They're only there for a millisecond and then they're gone. RBE on most of the newer, and older higher end, machines are only a rare occurrence. I think the benefits DLP gives you outweighs the disadvantage of having RBE showing up occasionally. The same can be said about JVCs DILA panels. You pick and choose which you value more and many can't be bothered by the things that bother me. Projectors are very subjective to end user and that person's opinion is the only thing that matters when making a choice on which one to get.

cheers rob

Turn down the sharpness and the RC as these add too many artifacts. You can also look at the reviews on Projector Central and Projector reviews and try their settings. Ultimately, each set up and projector are different but these suggestions may get you closer. You can also purchase a meter and software and do it yourself. It is an addicting hobby but one that has benefits to more than just your JVC. Enjoy the projector.

I don't believe there is a proper way to force the projector to show it at a lower hz without side effects (maybe). You can try watching at 60hz but it will add judder, or try inverse telecine maybe (cmd 5 I think). You will probably get used to 120hz if you just keep watching it.

my pointis, there are nothing but great reviews for the HD33, but in my experience they are ALL wrong !
plus i got my rs45 for just £400 more than the optoma

The original bulb exploded without warning in May, only 30 hours on it. But I was past the 90-day bulb warranty period, so add $300 for a new bulb to an already expensive projector.
In early October, I got the flashing light syndrome. Was told by Lorenzo White to send it to the Long Beach repair center. Spent $60 to ship across the country, received by JVC on October 19.
No response from JVC after receipt. Tracking site says "Waiting Parts". Two weeks pass, no change in status. When I inquire I am told the part won't arrive until December 26.
No projector for Thanksgiving, no projector for Christmas. Maybe I'll get it back sometime in early January.
I find it interesting that JVC describes this as a "professional" product. What professional would depend on a projector that takes ten weeks to repair in the first year of service? My Epson and Panasonic projectors never failed, in years of use, and are still on their original bulbs.
I sent Mikel at the JVC Customer Care Center an email a week ago politely explaining the situation. No response.
So that's why my first JVC projector will be my last. Expensive, unreliable, inadequately supported--at least that has been my experience.

Not sure how JVC normally handles it?

I've had experiance with Optoma and Mitsubishi projector CS and both were pretty good. Optoma was good many years ago (when I dealt with them) and Mits was even better----real good/excellent in fact.
In fact, in the Mits HC4000 thread a poster just got his HC4000 fixed for free even though it was beyond the warranty period.

it is well know that JVC produce great projectors, you will get the odd faulty one with ANY manufacturer..

I thought it would show up in the "Roomie" ap I bought for my Ipad, but it doesn't. When I try to input the PJ's IP address into the Roomie's "add Device" it doesnt seem to work.
I guess I will try it again manually.
