Use Dreamboxedit or Dreamset on your PC to receiver the scanned channels and then sort them as you like. Save and then send back to receiver. You can do the same with any existing channel lists.
If you use Lraizer's Auto Bouquets or the OE Alliance Auto Bouqquets Maker which is built into teh image, they will scan and bouquets like the official receivers within 2 minutes. They will not interfere with any existing bouquets.
