Christophe, I just updated the irFix firmware. When you have a moment please try it again.

While you may be the only one to report these issues (and you are technical enough to workaround them), I’d like to solve them for the sake of other potentially less technical customers. I appreciate your help.
RecordIRCodes() now only allows NEC-compatible codes, and I’ve rewritten the clock set functions. You’ll no longer need to hold down MENU to advance digits. You still can, but you can also mash MENU to advance the digits.
I’ll update the source on GitHub once we have this figured out.
