I tried several things after which I decided to try setting the JVC's HDMI color space setting from Auto to YCRCB 4:4:4. I did the same in the AVM50v.
I haven't had a problem since. Handshaking between the AVM50v (HDMI 1) as well as my Samsung BD-C7900 3D Blu-ray player which is connected directly to the projector (HDMI 2) has been smooth.
I am not sure if this will work for everyone but it is food for thought and worth a shot.
Anyone try this with a HTPC in the mix? I'm going to try it later today. My RS40 hasn't hung during input changes, but I do get an automatic switch by my computer's video card from/to 24p/60p as I switch inputs on the Octava 4x4 matrix switcher. It's the one troubling thing about my setup. It's fixable, but it sometimes requires some Octava switching to do so.
It's beginning to sound to me like the computer's video card is responding to the display it's connected to (via EDID?), and as I bring displays with different settings into the mix, it adjusts video output as needed to match the displays' capabilities.
This is probably the source of the frequent problems with my ATI video cards, as I switched back and forth among the RGB and YCrCb "pixel format" settings in CCC. It's just one more reason that I need a firm grasp of this whole color space issue. As long as the RS40 doesn't have problems with any of my sources when set to YCrCb, it might solve my issues, too. They're not as severe as having the projector hang, but they're annoying.
Edit: I really didn't understand how much a computer's video card communicates dynamically with display devices. As I go from using the the JVC with my HTPCs to my everyday PC monitor (a 32" Sharp LCD panel), the video card has to adjust its output automatically so that it can communicate with the 32" monitor - which has no 24p capability. Apparently, the RS40 has no problem with any type of RGB or YCrCb signal type that I throw at it, if it's in "Auto" mode. It may take a few seconds to resync, but it works. When I switch to the Sharp LCD for that computer, and the computer was outputting 24p, the computer has to change its display rate.
This may also be the source of the bug with my new nVidia card, where it sometimes switches automatically to 24p (though I still don't get that) and sometimes it won't let me reset from 24p to 60p in the nVidia control panel. This specific topic, though probably related, is probably more appropriate for the other thread.
If the less capable Sharp LCD monitor weren't in the mix, life would probably be a lot simpler.
