Enterprise Manager/RMAN Issues

I am having problems setting up the recovery catalog for RMAN backups in my environment. I have the following existing environment, DEV, TEST and PROD on 9.2.0.6 on separate SLES-9 servers currently being backed up and maintained using OEM 9.2(Java Client) on a different server with its OEM Repository on a 9.2.0.6 database. - Everything there works great. I have all the recovery catalogs on the OEM repository database and back it up last level 0 every night with its recovery catalog on the production database.  

Now, I am trying to add a DEV 10.2.0.1 database and OEM Grid Control v10.1.0.3 to the mix. I need to begin backing up this database and have not been able to get past the point of registering the 10.2 database on a recovery catalog. I have tried creating all the combinations of recovery catalog using RMAN line mode in my environment (9.0.1 from the EMGC oracle home, 9.2.0 from the other repository, 10.1.0 from an obsolete database install on my test server and 10.2 from my development server), every time in EMGC (web client) when I try to register the database (DEV 10.2) in the installed recovery catalog, I get an error that states:  

Incorrect Recovery Catalog Information          

Recovery catalog scheme version 10.02.00.00 is not compatible with this version of RMAN (or whatever version I installed)  

I have RTFM'ed as much as I could find and still am baffled, is there something (probably real simple) that I have missed in this mess. I haven't tried backing this database up using the 9i OEM, because the same thing failed when I tested it on a 10.1.0.3 database, so I think I am tied to the Grid Control backup process.
