I have noticed something very strange using Mitsubishi/Samsung 3D Glasses - not really an error - but wondering if anyone can explain it. I have a number of STB and other pieces of electronics in the same room as my 3D-TV. While viewing 3D programming, I noticed that the blue ring, power, resolution and even the record LED "sparkled" on my HR-20, HR-21 and HR-23. Upon closing one eye, its obvious what is happening. The lights all cycle in 1 second cycles, going from full off, growing in brightness, peaking and then declining in brightness. The left and the right eyes are offset in the cycle, giving the "sparkling" effect one sees with both eyes. To make it even stranger, NO OTHER ELECTRONICS LED shows this effect. This includes the H2x DirecTV STBs. To me, as the glasses cycle 120 times a second, it really makes no sense to me why this is happening in a 1 second cycle - and even stranger that the L&R cycles are out of phase. Can anyone explain what is going on - and why are the Directv HR2x units the only electronics to show this? Also, can anyone tell is it happening with Panasonic 3D Glasses as well?
