Common! I have only had Voom for 24 hours and I've noticed it many times.
I think it's #1. I have the newest hardware available (came with the latest software already installed) and I have the microstutter.
If I really cared about what you might think, I'd do an extensive study to find which channels and when it happens. But, in this case, I don't. Sorry.
1. Your eyes are not trained enough to notice these somewhat subtle artifacts.
2. You have a newer box than what the rest of us have and the problem could have been corrected in the newer hardware.
