After we told him we could not move the receiver away from its location under the t.v., which apparently, Panasonic thinks would help, he mailed us an IR Filter to put on the Onkyo. It was about 1" x 1" hard plastic. We sprayed it with a solvent to stick it on the Onkyo's IR location, as it was not self-sticking. The solution worked. Now, we can control volume on the Onkyo while the Panasonic is in 3D mode.I am still wondering why this situation arose

Above posts edited for brevity, just to provide context:
There is simply too much stuff to test to catch all instances of possible interference, especially as new designs hit the market in a short time frame. I would bet that both Onkyo and Panasonic did test in their labs for possible interference from/to all known sources and devices using a IR-blaster mockup (with software-configurable IR signals, including 3D glasses sync flooding) and IR-receptors.
But the lab is not the real world, and although the filter worked for WendyH, it might prevent other folks from using their Onkyos in their particular installations by attentuating the IR signal too much, or by blocking IR from third-party IR controllers like a Harmony. So Onkyo might not want to make the filter part of the standard IR sensor sub-assembly.
Most people seem to get lucky with receiver and 3D xmitter not interfering, and hopefully this problem will diminish as 3D glasses sync methods migrate to using Bluetooth, and perhaps IR filters can get more selective.
It would be interesting to see a study done on how sensitive IR sensors (e.g. in receivers) are to the various IR sources, and how prone specific IR sources are in causing interference in a variety of sensors. We might see whether one manufacturer is the culprit in either category - who's too sensitive, and who's being the bully.
On a completely unrelated note, I ran Audyssey last night but was dis-satisfied with the EQ results: the Onkyo implementation of Audyssey that has the high-freq roll-off ends up sounding too muddy in my relatively-well-treated room, and it wreaks havoc with the nicely EQed BFQ-subwoofer combos. So Audyssey is disabled. Too bad Onkyo doesn't allow the Audyssey Flat curve and that Audyssey won't allow the user to disable EQ on specific channels (like the SW).
I did use the speaker distance and relative levels though, and tweaked the speaker crossovers up a bit (let the SWs do their job).
