Drop the "Video, VBI and RDS Looping" section, instead moving the
Video/VBI info to section "Video and Sliced VBI looping" and the
RDS info to section "Radio & RDS Looping".

-Video, VBI and RDS Looping
---------------------------
 
-The vivid driver supports looping of video output to video input, VBI output
-to VBI input and RDS output to RDS input. For video/VBI looping this emulates

-and VBI looping is only supported between S-Video and HDMI inputs and outputs.

 Looping is currently supported only between devices created by the same
 vivid driver instance.

 The way to enable video/VBI looping is currently fairly crude. A 'Loop Video'
 control is available in the "Vivid" control class of the video
 capture and VBI capture devices. When checked the video looping will be enabled.
