My wife is not one to complain about picture quality. She routinely watches SD channels with no complaints. But today was different. As a stay at home mom, she's been flipping around the dial and recently has been watching programs on Lifetime HD (252) and noticed numerous flickers/black flashes. And I have to agree. After watching a few programs off the channel, I'm seeing the same thing: the picture quickly blacks out, then comes back in a fraction of a second. At first, I suspected an HDMI handshake issue, but it's recorded on the program, and completely repeatable when rewinding. The audio never drops out, only the picture...and only for a fraction of a second, but several times per show. Are we the only one's seeing this?
