RV,
That is why I considered HTPC as a last resort for my system. Fortunately, I just secured a deal that will keep a HTPC out of my system forever. Smile

I may still use one, but it won't be my main component.

How many drivers and codecs and other stuff do you have on your computer? Maybe I am missing something, but I don't think there is a lot out there that you need.

I might add that I have been running my HTPC into my Sony direct view CRT. I use the HDMI port with no problem. I use Vista with an AMD 5770 and Ubuntu with Intel on board graphics. I have a 2500k Sandy Bridge CPU. I did have some set up issues with the AMD, but it has ran fine ever since.

My rs56 arrived late last week.

I had ordered a Chief mounting plate that is compatible with the Chief mounting bracket that I had installed for my Dukane 9015 projector. Removing the old plate and attaching the new plate designed for JVC projectors was easy. The nice thing about this was the ability of the Chief mounting bracket's multiple adjustments. Unlike the Dukane mounting plate, the JVC has four (rather tiny) screw holes in the four corners and it was work to hold this projector up at my 10" ceiling and then line up the holes for the screws. It took two of us . The Dukane mounting plate had two slide-in slots (one at a 45 degree angle at the back side) that i could simply loosen the legs of the projector and slide them into place...easy for just me to do. I could then tighten the projector's legs and then set the locking bolt and that was it.

Considering the cost of the Chief mounting bracket I would probably have gotten a metal plate and drilled four holes and then used the JVC feet to slide into the holes and then mounted the projector. Tightening the large feet would have been much more simple and, instead of holes, I could have also cut slots for two of the mounting feet and have full versatility and ease of mounting as I did with the Dukane mounting bracket. i did go to the hardware store and substituted the phillips screws with allan bolt heads. Better than using a phillips screw driver, especially when tightening them.

Someone around here will smile now that I have retired my HDfury.

Although, I do have to admit that the old Dukane/HDfury set-up served me well.

More thoughts on the JVC unit, later.

MPC adjustments work really well on HD broadcasts from Dish Network. Not so much on standard broadcasts. I have my Anthem D2 at another location and I am interested to see what it can do to hel[p. When I use my Anthem to boost the Dish HD feed up to 1080p on my plasma, this is a nice improvement.

One thing for sure, my OTA (off the air) HD broadcasts are much sharper than the diluted feed from Dish Network. I agree with others that the factory settings on the RS56 don't need much adjusting. If anything, casual adjustments from the remote, like brightness are not an improvement.

I have not tried 3d yet. Perhaps this weekend.

I have yet to notice any fan noise whatsoever.

I haven't actually looked into this (probably should, but I'm currently busy with other stuff), but here's a brain-teaser question for JVC folks. (Or trivially obvious, if you've have one, set it up like this, and already know.)

If you have the PJ centered horizontally on the screen (allowing max vertical offset), zoomed in for the max size at a particular PJ distance, and are using max vertical offset to have the PJ as high as possible w.r.t. the screen. When you zoom back out, reducing the image size, does the image center move up, down, or remain stationary? Or another way of looking at it, what's the anchor point?

Good question Tim - I don't remember. I believe the picture moves up as you shrink (zoom out). Why do you ask?

I believe that this projector is much more sensitive to being placed more even with the top of the screen as tilting the projector down to fill the screen creates more distortion than with my previous projector. I hung the RS-56 in place of my previous projector and notice I can't get quite the same picture with perfect right angles.

This is only obvious when I use the set-up lines, not really when viewing.

I am fortunate that the Chief mount that I use incorporates a brass pipe that I framed into the ceiling of my addition. I can unscrew this pipe and put in a longer pipe so as to not have to tilt my projector.

I was probably going to live with the tilt until I saw your post. My addition is framed with ten foot ceiling so I don't want to raise the screen.

I rented Marvel Comics The Avengers in 3D last night. It took me a while to sort out the 3D settings. The glasses come with a single piece of paper consisting of safety precautions, warranty and small set of instructions--small print in three languages.

Included is how to Register--pairing-- of the glasses to this projector. Pay attention to the part about "with 3D images ready for viewing..."

Since I did not know what to expect it took me s while to get it right. I am very glad I can watch in 3D. Great effects. The glasses are a bit annoying; I can get used to them.

The Avengers is the second of only two movies I've seen in 3D in a commercial theater, Avatar being the first. I have to say that seeing The Avengers really warmed me to 3D. I'm looking forward to watching this one in my theater. Thanks for the reminder!

In Avatar some scenes are really good in 3D. Others seem to fade a bit. Maybe this is the nature of 3D.

Oh, I just ordered Avatar. I found a really good on-line 3D rental service.

I control my jvc rs56 projector using rs232. When I query power state I receive a power on response too soon. It takes another 20 or so seconds before the lamp lights and the projector is operational.

Is there an rs232 command that I can use to ascertain when the projector is fully ready?

Is there an update to the rs232 /LAN/IR control manual that covers the rs56?

Are you using an AMX/Crestron controller? I have written some AMX control programs and there is a WAIT statement you could use while the JVC opens the lens cover, energizes the lamp, etc to avoid sending the projector anymore data during start up.

NO, I have a PC that controls the Theater and have basically implemented what you say Crestron has. After power on is returned as status I wait 20 seconds and that seems to work correctly. I was just wondering if JVC added an additional status query such as "Lamp Ready" to their protocol. It would be nice. I was also looking for an updated protocol document that included the RS-56
