I have a Wharfedale tv. After lots of messing, I have found that the Universum TV Keyset 1 works-ish. Power button works, Mute works, Volume down works but the Volume up key brings up the menu. However, the Info button under Utility DOES turn the volume up. If you're planning any further work on this program I would be very grateful if you could add a simple Wharfedale keyset with just Power, Mute, V-up (Info) and V-down.
Thanks
