Any of you guys experiencing what appears to be a quick signal loss from KGW while in HD? I rarely watch it, but while watching SNL and Crossing Jordan, my 811 goes black for just a split second, loses audio then tunes back in as if I had tuned the channel in and I get the Info browser banner at the top as if I had just tuned the channel. I haven't tried my Voom or 6000 yet to see if they do it as well.
