OK, so question.
I sit about 11~13 ft away from the screen at a pretty much straight on angle.
I notice the CE5s are losing sync or doing something where the color of the whole screen tints a single color. Seen a red-pink or two, but mostly yellowish green. Lasts for a few seconds then goes back to normal.
I haven't be able to narrow it down to anything in particular.
I watched a few minutes of the free 3D bit on cable, Haunted Castle. It did it quite often. I could clearly see two different images as if I wasn't wearing the glasses, but there was unusual color tinting when it lost sync. Almost as if watching an anaglyph 3d.
So I tried a few minutes of Ice Age 3. Played fine without any issue.
Then I switched on Coraline, and it started doing the same thing.
As far as I can tell it has to do with darker scenes. I turned off the lights in the room and blacked out the window as I read lighting can have an issue. Played with brightness, color, contrast, but can't seem to do anything about it. Sometimes the glasses lose sync entirely.
Added notes -
Well, I contacted RealD, and got 2 responses, haven't heard back from them since. After playing around with the, I can reproduce the problem in various scenes. I also pulled up a chair and sat closer. At 9ft or less I appear to have no sync issues. Seeing as how i can reproduce the problem in various scenes of a couple of 3D films I've been experimenting with. Really not looking to push the couch a few feet closer as not only screws around with optimal distance for the TV, but would crowd the coffee table and kinect play space >.> Time to report the distance issue to RealD. Maybe they can fix this!
