    No, what I'm talking about isn't film grain or grain on a transfer
    medium - besides I would assume the pro's do it through through lenses
    for the best possible resolution, not using a screen.

    What I'm talking about is where there's an area of say a black, gray,
    etc. area where instead of a smooth graduation of brightness from
    light to dark, it's like there's a pronounced "shelf" of brightness,
    anything that's above a certain darkness shows up as this sort of
    grainy, lighter cluster or "cloud" of pixels that contrasts with
    anything that's below this darkness threshold around it.

    I used to see that stationary grain all the time from early CCDs. There
    were telecines that shot the film right onto a CCD.

  3. From our local cable company (Time-Warner), we often suffer with
    SD material what looks like excessive JPG compression artifacts
    along edges, similar to what one sees when overcompressing a still
    image with tree branches in a sky. We get the "wubblies" in the
    smooth tone areas intruded on by areas of higher detail. Quite
    annoying visually, and likely due to the jamming of too many SD
    channels into too little bandwidth using JPG compression rates that
    are too high for good quality. Fortunately, the HD material suffers
    not at all here from this (except for the occasional picture black-outs,
    picture "blocking", sound garbling and collapse, and other delights
    of the "superior" digital TV system we are now forced to experience).
