I have my Dish Network VIP922 connected to a SlingCatcher.  Dish has brilliantly removed the Virtual Remote controls from both the Sling devices and even there own Dish Online access making control of the DVR impossible.  I thought I could teach the SlingCatcher remote via learning the Dish VIP922 remote but it will not take the Guide or DVR functions.  It will learn Volume and Mute.  Any suggestions or is there an upload for a BIN file for the VIP922?
