Looks useful.  My post was really to suggest that using the Transport 
editor might avoid the need to write directly to the DB, but you might 
not need to set those params anyway.  Just deleting satellite channels 
and rescanning known transports might do the update; if not you might be 
able to set to 'auto' and rescan.  Or maybe not...
