The fourth number is relevant.

In your config, the number is encoded in the pre_data_bits (You have 2 bits of
pre_data, and 11 bits of normal data in your original conf).

Because the pre_data is different for those two codes, I needed to redefine it
to 13 bits, no pre-data, and include the old pre-data in the code.  (Which is
why all of the codes are now of the form 1XXX instead of 0XXX)

At least on my machine, the config I sent has no problems distinguishing between
Mute/Move and Up/Down.

Admittedly I now have U/D mapped to the same functions as CH+ and CH- now, since
when watching a recording, up/down are now mapped to skip forward/back 10
minutes in 0.14, but the config I sent allows someone who wants to use U/D for
something other than CH+/- to do so.
