I cheaped out and picked up the PS3 glasses and actually ended up liking them better than the RF ones anyway. I also tried the Cat-5 to the front, but for some reason I just can't get the emitter aligned correctly to transmit the right signal and I'm back to poor sync. So for now, I just make sure volume and other settings are good to go before starting a 3D movie. I'm also using a programmable remote with a quick-jump button so I can switch back and forth between 3D modes. When I do this I can switch off 3D, make any changes to volume, and then back to 3D in a couple of seconds.
Would love to hear if you have success with the cat-5 method.
Bummer that your external emitter wasn't able to reliably sync the glasses. My prime rationale for adding one to my set-up would be to allow viewers to watch in the back row of my theater. Intuitively it would seem placing an external emitter above the screen would pretty much guarantee an improvement in the signal strength reaching the glasses, assuming that the signal strength of the external emitter is at least comparable to that of the built-in one.Right now the signal from the emitter in my projector has to travel 15ft from the projector to the screen, reflect off that screen and travel back past the projector to the back seats, about an additional 17ft of extra travel. If I place the emitter above the screen, I eliminate the first 15ft of IR travel and the signal only has to travel the 17ft from screen to back row. I'm still mad at Sony for not going with an RF solution!
I do believe that a new receiver has the potential to fix the problem of not being able to adjust volume in 3D. I use a PS3, with an external dongle that convert IR to Bluetooth. That dongle is also fed an IR signal through my IR repeater and that still functions during 3D. Either the dongle it better at ignoring the IR interference or the stick-on flasher is better positioned. I may experiment with moving the flasher to my Receiver around. Also, the receiver I'm looking at has the ability to be controlled from a Smartphone via a local network (Ethernet), although I worry that the latency associated with that type of control might be unacceptable for normal usage.
I'm not sure if I want to go through the extra effort and cost of adding a flasher. I have a couple unterminated Cat-5 lines run from the projector location to the equipment stack (in a utility room at the side of the theater). Based on your experience, I'm skeptical that a side-on location for the emitter would work at all well. If I want to get the emitter to the screen, I'm going to have to run some exposed Cat-5 cable from the door of the utility room to the screen. I'd have to use a Ethernet extender (which the manual says not to do) and I'd be able to hide most of the cable run, but not all of it.
If I had a local dealer who could loan me an emitter I might give it ago, but otherwise I'm hesitant to spend the almost $100 on something that might be unusable.
