So it was responding to some button presses prior to installing LIRC? Sounds like maybe you have two programs responding to button presses! Try removing LIRC and see if it's back to only responding once and go from there. If it stops altogether then reinstall LIRC and see how it does. Irw can be used at the commandline to see what LIRC is receiving. You might also try a REAL MCE remote, in the past I've had issues with programmable remotes and have had to program them FROM a real MCE remote to get proper operation...
