Exactly...  To see the cards/sources from the missing backend, the OP 
would have to make Myth think he's running on that missing backend 
(which is likely to cause problems because of the different/missing 
capture hardware).

Besides, the approach I gave cleans /everything/ up.  I like to think of 
that approach as the same one I use when someone gives me a MS Word 
document to format--rather than trying to undo the things they've done  
incorrectly so I can do them correctly, I just save to plain text, then 
format it correctly from the start.  It's a /lot/ easier to ensure 
everything is properly defined when you start from a known state.

And, really, defining capture cards and connecting inputs takes me all 
of 30 seconds with my setup (with 2 backends having 2 capture cards 
each--whose inputs need connected in a specific order to spread out the 
load).  Defining my video source (OTA digital) takes me all of about 2 
minutes more than the full channel scan itself takes.  (And, see 
http://www.mythtv.org/wiki/Database_Backup_and_Restore#Backup_xmltvid_data_.28before_doing_a_full_channel_scan.29 
and 
http://www.mythtv.org/wiki/Database_Backup_and_Restore#Restore_xmltvids_after_a_channel_scan 
for a way to make it a bit easier.  Note that I'm going to eventually do 
a much better implementation of the channel fixup--just need to make 
some time.)

Sure, if you're out of practice it may take a bit longer, but still, it 
shouldn't take too long.
