Well, if irw shows buttonpresses you are almost there.  The last piece
in the puzzle is lircrc, which maps the irw buttonpresses to
mythth-specific strings.

Since yiu are upgrading, you should already have a lircrc file
available. The next test tool is ircat, which sort of mimics mythtv. Use
it like
   $ ircat -c ~/.lircrc -mythtv

It should emit key strings as defined in the lircrc file.

There could be two possible problems:

    - The lircrc file does not or mythtv does not find it.
    - The button symbols used in lircrc does not match the irw output
(i. e., the lircd.conf file)
