I have the Slingbox Pro Hd and using with Directv Mini Genie C51-700 and remote RC73. I cannot fine either option when configuring for a virtual remote. I have tried many others but cannot get the channel to change. In fact the only thing that does work is the volume control. I did change the box to operate in IR mode and have the IR blasters positioned correctly. Does anyone know what device will work or if I can import my device?
