"Older version of mythbuntu" says it all - there have been big changes
in how IR receivers work in the kernel, and likely your old config is
for the old way and needs significant updating to work now.  The
driver for the MCE remotes has been moved into the kernel.

So what is your config?  You might like to take a look at my working
Mythbuntu 14.04 config for my "SMK Manufacturing, Inc. eHome Infrared
Receiver" and my Hauppague Nova-TD 500 and HVR-900r2 IR receivers.  It
uses the new devinput driver and is available on my web server:

  http://www.jsw.gen.nz/mythtv/mythbuntu-devinput-lirc.bz2

Read the README file for some help with how to configure and test a
devinput lirc setup.
