For those with Samsung TVs, are you guys using Digital Clean View when watching so-called HD cable? I've found that the PQ is pretty awful with it turned off, especially in darker scenes. The two biggest issues seem to be mosquito noise that is constantly moving around in the background, and also on people's faces. The other thing is the block-type artifacts. I'm sure my 65" TV just magnifies the effect, as I don't remember it being nearly as offensive on a smaller screen.
Anyway, bottom line (unless there is something wrong with my equipment) most of the channels look like crap. If I turn on DCV, it makes a significant difference, but at the expense of a little blur. I'm still wondering about the best setting—low, auto or something else?
