Then you can either do a full scan, or do a scan all existing transports. I forget the options now, but you can do a new scan while keeping existing channels - thus you can scan all your transports and you won't get anything for those that are on "the other" antenna position, and then do another scan to get those other channels.

Again, this all goes back to my original question.  The option to NOT
delete channels, at least as I remember it, was based on the "Existing
Channel Treatment" option, which included "Minimal Updates" for this
purpose.  When I went to do the full scan yesterday there was no such
option (unless I'm really blind).  If this is still possible, I'd love
for someone to tell me how.

Otherwise I may need to simply rescan existing transport frequencies
one at a time...though I'm not totally clear on that one yet.  I'm
assuming that wouldn't affect anything but channels assigned to that
mplex.
