Try using this portal address
http://portal.iptvserver.tv and use simple client PVR configure this address in simple client pvr
http://localhost:8899/channels.html?portal=1 enable live tv and let kodi populate the channels and guide. Configure iptv stalker with your valid mac adress and portaliptvser.tv as i written it at beginning. Your guide and Stalker should both work. On the guide you will have to offset time shift -5 hours for guide to be right. I could never get stalker PVR to ever work with any setup myself. but this works great when their servers is working right.
