</div></div>The <mythtv user> bit in the file path is a placeholder for whatever<br>
user name you use that runs mythfrontend. Mythfilldatabase, in my<br>
system, is run by that user. I do not use the standard system for<br>
running mythfilldatabase though, so I am not entirely sure if the<br>
.xmltv file needs to be in /home/mythtv/.mythtv (if mythfilldatabase<br>
is run by user mythtv) or in /home/<mythtv user>/.mythtv (if it is run<br>
by the user that runs mythfrontend). To be safe, I think it should<br>
probably be put in /home/mythtv/.mythtv, and then these commands used<br>
to put a link to it under the mythfrontend user:<br>
<br>
cd /home/<mythtv user>.mythtv<br>
ln -s /home/mythtv/.mythtv/<your .xmltv file>.xmltv<br>
<br>
The name used for the .xmltv file needs to be the name used for<br>
defining the MythTV "source", with the .xmltv extension added. My<br>
source is "FreeviewHD" for my DVB-T channels and "SkyNZ-Digital" for<br>
my DVB-S Sky channels. So I have two .xmltv files:<br>
<br>
/home/stephen/.mythtv/<wbr>FreeviewHD.xmltv<br>
/home/stephen/.mythtv/SkyNZ-<wbr>Digital.xmltv<br>
<br>
The case of the filename must match.<br>
<br>
In your case, if you are doing your EPG the same way in 12.04 and<br>
16.04, you should already have the files in your 12.04 setup in the<br>
right place, so the simple thing to do is to just copy them from there<br>
to the same place in your 16.04 system.<br>
<br>
The channels in the .xmltv files vary depending on what is available<br>
in each part of the country, so just copying mine would not work<br>
completely. And every time a new channel appears or one is renamed or<br>
disappears, you have to make the corresponding change in your .xmltv<br>
files manually, unless you completely delete all your channels and set<br>
them up from scratch again (not recommended). The tv_grab_nz-py EPG<br>
grabber does not have the ability to modify the .xmltv files, but<br>
IIRC, it can create them on initial setup. But it is a long time<br>
since I used tv_grab_nz-py like that, as I do my channel setup using<br>
other means, so I may be wrong about that.<br>
