I've been using Media Center 15 and finally decided to evaluate the latest version (i.e. 20). I also tried downloading Gizmo on my Android phone to use as a remote and would eventually like to install Gizmo on my Nexus 7. So first I tried Gizmo using the original MC 15 and all the basic functions worked except the "now playing feature" which seemed to get out of sync. And I was able to adjust the music volume using both the phone volume control and the command window. However, when I tried to do use Gizmo with MC 20, the "now playing" issue was fixed but I am no longer able to control volume. When I try to adjust using either the volume control or the menu I get the message "Volume: N/A". I would guess this is a configuration issue (I hope?). How do I fix this?
Also, are there any differences that I should see using Gizmo on my Nexus 7?
