Thanks SurfR and Dave for the clarifications.

Of course if in a year I get lots of new equipment then I guess it would be a drag not to have access to updated codes in the software -- learning commands is a bit of a drag but doable.

Question: I have downloaded a file (not thru URC) that has all of my Panasonic AE900 codes. What's to stop those kinds of files from being shared on the web to people who can't get the "official" codes from URC? They don't seem like those are copyright issues.

And it's fine if you want to tell me to slog through thousands of post . . . which I probably won't do since it sounds like my MX850 will stay programable for me.
