16 X 9 Programming & channel 21-4  On December 17th WXXI started
converting all programming from a 4x3 aspect ratio to a 16x9
ratio... this means that programs viewed on a 4x3  (old style
set) will be letterboxed.  This means the picture will be
smaller and have black bands at the top and bottom.  Some
programs are still being fed to WXXI from PBS already in a
letterbox format this adds even more 'black' area on the sides.
 If the viewer is using a set-top box, there is a feature that
allows the viewer to 'zoom-in' to improve the picture size.
During this transition channel 21.4, known as our standard
definition simulcast channel has been discontinued, as all
programming is not available on digital channel 21.1, cable 11
or digital cable 1011. YES!  WXXI is broadcasting in a digital
format available on cable and over the air.    How come my new
converter box signal keeps flipping on and off?  Two of our TV's
are on cable, so I don't have to worry about them.  Our third
little TV in the corner of the kitchen
