What purpose do the controls serve on the viewer?
The OnGuide/TV button is located at the top left corner of the InStream dashboard. Clicking on this button toggles between “TV” mode and the “OnGuide” program guide mode. In onGuide mode, the viewer window displays the list of available channels and up to two weeks of detailed program information for each channel. When InStream is in TV mode, video appears in full-window mode and the button reads onGuide.
