Use the editor itself rs232 to get the .udf file from receiver or use the hacked version that opened .dbs files.
alieditor.ini must be set to chip type =m3602 or you will never see the tabs for ac3 or h264.
some were set to chip type=m3329c which was wrong for that receiver.
The mst firmware tool will also extract the .udf from the full 4meg .abs
it is up to ver 0.5 now
there was also a split/merge program with the stbhd editor that would split off the .udf from .dbs so you could edit.
Then merge to get the edited file back to .dbs format.
I leave the rs232 and lan cable connected all the time,so I just use those to grab the channel list from stb.
