Welcome. I forgot to mention that you can create the satellites.xml to your liking here: [Only registered and activated users can see links. ]
Let me know if you have any installation issues and i will try to help. Should not be hard to do, but a group of files may need to be broken down, then your satellites.xml installed, and the files put back together (unpack/pack). Not 100% sure, but I think enigma2 channel editors will work on the A3 if the correct path-to-files is used.
