John;
All my specs are on another computer. I will refer to them in short order.
However, by dividing 480 by 9, one gets 53.3. Multiplying 53.3 x 16 one
gets 853.33. Kinda funny to call that a display aspect ratio of 16x9, isn't
it? I need to refer to 13818-1 before I address the sample aspect ratio.

Oh,
