I tried with the settings in PVR Stalker Client alone with Stalker App Send Serial and Custom serial Disabled and I still get unable to load channels. When I have the Custom serial enabled I can freely watch the Channels as long as I select the channels through the Stalker App. But I cant load Channels through PVR Stalker Client. What am I doing wrong here?
You need to have the same settings in both IPTV Stalker and PVR Stalker ("Stalker Client") to have both work. In IPTV Stalker to reveal the fields, you need to have "Send Serial Number" and "Custom Serial" on, and use the identical settings in Serial Number, Device ID, Device ID2 and Signature, in Advanced in "Stalker Client". You probably will need a new MAC, or at least unlink and relink your MAC after you first configure those addons.
What irish girl is saying though is that you do not have to have IPTV Stalker, especially if you don't need it. I'll only recommend IPTV Stalker for those who need to run an external EPG addon, or can't update to Kodi 15.
