I have the ME over the pond in the UK running AZtrino 1.6. Anything it finds in a blind scan is saved in a 'services' XML file leaving the 'satellite' xml file untouched. For me that's great as I can just delete the 'services' file then redo the blindscan without it clogging up the satellite xml file with unwanted transponders. which become dead.
You have to reboot however everytime you blind scan else it screws up, hardly ideal, still some way to go I think, but at least it does work whereas Enigma 2 blindscan will only lock in high band transponders and ignores anything in low band.
