Hi rhurbarb,
I've never really bothered messing around with manual transponder editing because,I've not found the need to, nor do I have a DM-7000 to check what you are talking about.
After installing the motor, what I did was to scan all the sats I could for every service I could pick up using a Multi Sat Scan.
I then downloaded all services/bouquets from the DB using DreamboxEdit, imported the bouquets from The Captains Settings (Similar to pet settings) into DreamboxEdit, and loaded this back on to the DB.
I did have to do some tweaking because there were some changes in services/packages between the time The Captains Settings were created and the time I loaded them. Also to add my own bouquets.
You could also load all of the service files etc to your DB without bothering to scan the satellites or import bouquets, This is a bit messy because it potentially leaves you with a lot of services listed on your DB that you cannot actually receive because of location / dish size etc.
It takes a while to get everything close to how you want it.
Make regular backups of your settings to avoid all this hassle in the future.
With backups of your settings available, you can flash a new image to your DB and have all the services/bouquets up and running in under 15 minutes.
Hope this helps,
C
PS: I can see into the future and predict that there will be some questions about EMU's or CS soon
