The <mythtv user> bit in the file path is a placeholder for whatever
user name you use that runs mythfrontend.  Mythfilldatabase, in my
system, is run by that user.  I do not use the standard system for
running mythfilldatabase though, so I am not entirely sure if the
.xmltv file needs to be in /home/mythtv/.mythtv (if mythfilldatabase
is run by user mythtv) or in /home/<mythtv user>/.mythtv (if it is run
by the user that runs mythfrontend).  To be safe, I think it should
probably be put in /home/mythtv/.mythtv, and then these commands used
to put a link to it under the mythfrontend user:

cd /home/<mythtv user>.mythtv
ln -s /home/mythtv/.mythtv/<your .xmltv file>.xmltv

The name used for the .xmltv file needs to be the name used for
defining the MythTV "source", with the .xmltv extension added.  My
source is "FreeviewHD" for my DVB-T channels and "SkyNZ-Digital" for
my DVB-S Sky channels.  So I have two .xmltv files:

  /home/stephen/.mythtv/FreeviewHD.xmltv
  /home/stephen/.mythtv/SkyNZ-Digital.xmltv

The case of the filename must match.

In your case, if you are doing your EPG the same way in 12.04 and
16.04, you should already have the files in your 12.04 setup in the
right place, so the simple thing to do is to just copy them from there
to the same place in your 16.04 system.

The channels in the .xmltv files vary depending on what is available
in each part of the country, so just copying mine would not work
completely.  And every time a new channel appears or one is renamed or
disappears, you have to make the corresponding change in your .xmltv
files manually, unless you completely delete all your channels and set
them up from scratch again (not recommended).  The tv_grab_nz-py EPG
grabber does not have the ability to modify the .xmltv files, but
IIRC, it can create them on initial setup.  But it is a long time
since I used tv_grab_nz-py like that, as I do my channel setup using
other means, so I may be wrong about that.
