Joe,

The manually programmable remotes are less frequently used by installers, and as a result, less answers to be provided by the installers here. I haven't installed a manually programmable remote in about 10 years, because the PC programmable models are much faster to program, easier to adjust programming on, and are easier to update. Nothing against the MX-450, of course. Everything has it's place.

That being said...have you tried learning the commands from the new cable box remote to the 450? That's one of the major selling points - it doesn't become "obsolete", since you can always teach new commands to it that aren't in the database.
