You can remove any unwanted content from your guide by going to TiVo Central/Settings & Messages/Channel Settings/Channel List. Remove the check mark from all channels you don't want to see, then hit the OK Button on the top of the remote. Once you are back on Live TV, select the Guide Button on the remote and then the Yellow A Button. You'll see the options to sort the Guide by My Channels, All Channels, or Favorites. Select My Channels and then the OK Button and you're done, no more Fox News!
