I just got a Slingbox SOLO and connected it to a Motorola cable set-top box that is part of a Verizon home media (multi-room) DVR system. I can access the DVR and watch recorded movies from this set-top box but cannot access the DVR from my Slingbox. When I configured my Slingbox and put in the correct set-top box model number, the remote that came up on my computer screen works fine for watching live TV and changing channels, but it does not even have a DVR button and the Menu button does not work. Help, please!!!
