Oops, I'll try and switch up my posting :)

No I don't have a simple solution.  My box now will compile so it now is
simple, but if it were to die getting it back to the correct configuration
would be a hassle I am sure.

How do you know what an "unwanted" transport is? I guess you probably have
more familiarity with the signiling side than I do currently.  My knowledge
stops at... I expect QAM on my unencrypted channels... and I assume
Transports to be different frequency ranges for the different channels?

Also you mention a linked scan?  I have only done a full scan, and
attempted to import a scan.  Is a linked scan another option that perhaps I
can try?  What does it do differently?
