I for one would appreciate a file for the 1400; most of the codes for the 1000 from the database worked for me, but I can't find a code that works for the exit key, and for some reason I can't train my MX-3000 for that particular key (all of the other ones that didn't work from the database were learned properly). I've tried all of the usual tricks (different distances, tapping rather than holding down the key, using a book to act as a "gate" for the signal) with no success. Not having an exit key makes using the MX-3000 for the BD-P2550 a pain.
