Believe what you want...I just speak with facts.... No EPG Source for these channels available.
And yes, you can assigne wrong EPG Source to a channel to believe there is a EPG Source...:
use the XMLTV Link in the field....
XMLTV: http://clientportal.link/xmltv.php?username=000000&password=000000
Replace "000000" With username and Password from your M3U line
For Planet HD is no EPG source right know, thats the reason.
Just let it EPG field empty and click enable Detect EPG.
Then EPG source will come from SIPTV Portal.
FYI : I hate this app.... :D
