[mythtv-users] Can't get lirc or irw to work, but mode2 works

[Jerry Rubinow]

I tried reinstalling mythbuntu 14.04 again, same issue.  Uninstalled lirc,
didn't help.  I tried upgrading to Ubuntu 15.04, but same issue with the
irregular scan codes.

I tried installing the beta of Windows 10 and a Windows build of
mythfrontend from here, http://sourceforge.net/projects/mythtvwindows/

Mythfrontend started up and recognized button presses on the remote.  So
it's not a hardware incompatibility between the IR receiver and the LIVA.
I tried two different MCE remotes and both cause the same issue with
scancodes.  I've googled a lot and I haven't been able to find information
about trouble at this level.
