Sidebars
The parameter, which is hidden if 3 Video Output is not set to Sidebars, adjusts the sidebar
position where the center video meets the pillarbox background video on both sides.
The underlying hardware feature is the same as Custom Right Crop and Custom Left Crop.
This is effectively an extra handle on the Left Crop and Right Crop parameters.
The Crop and Sidebar Edge controls are additive; increasing Sidebar Edge (making the
sidebars larger and the center-video smaller), equates to setting Left and Right Crop
values to smaller percentages. The Sidebar Edge can be set to 0 through +128. A value of 0
produces a 4:3 center. Positive values produce wider sidebars (and a narrower center).

0 to +128 (Variable) Defaults to 0. Select a width value from 0 through +128 to expand
or shrink the sidebars, which are filled with Background video (4
Background Fill). Selecting a larger value causes the center
picture to become narrower while the sidebars expand.
