I think I am getting somewhere. Opened DreamboxEdit and after setting my box IP address in it, I hit "Retrieve files from dreambox". After I got all the channels on screen, I highlighted them all and hit "Number all channels". I then also copied them all to Favourites bouquet. After many failed attempts sending files to dreambox by hitting "reload settings on dreambox", I finally hit "Send files to Dreambox" and yes all channels were now available in the favourites bouquet and with channel numbers!
I can press a channel number and it will change channels but still no joy in having the three --- change to channel numbers. I have been in the blue panel a couple of times under OSD and also under EPG.
Thanks a lot, it is a learning curve
