Thanks, I'll take a look at your config, maybe it will shed some light.  To
be clear though, the config on my old computer is not the issue.  I did a
clean install on the new computer - didn't migrate any settings, wiped the
disk.  So the default mythbuntu 14.04 did not produce a workable
configuration.  I also tried uninstalling lirc and just dealing with
ir-keytable - I'm not as familiar with that as with lirc, but the raw
scancodes looked damaged.

Thanks for straightening out my top posting, btw.
