Could anyone help me on what the square/ stop button does when on the tv guide? It says at the bottom by pressing square/ stop on the remote it jumps to now? Now I assumed it means I jump to the channel on the tv guide that I am watching live. So as an example, I'm watching Sky Sports News, I hit Guide on the remote which brings up it up, always starting at Number 100 ( Must See Virgin TV ). I hit the jump to now icon but nothing happens.
