yes its needed,thats where iptv simple client gets the channel list from(not needed if your not using iptv simple client).personally I leave iptv stalker enabled and just disable pvr stalker when I want to test iptv stalker.when I want to test prv stalker I disable iptv simple client( u cant have 2 pvr clients enabled at same time anyway).
the only way u can get the double login going is say if you are watching pvr stalker and goto video addons(since iptv simple client is disabled) and select a program that way,and even then I doubt it will be a double login as soon as u select a show via iptv stalker, pvr stalker stops playing so the show u selected can start.
I use same mac for both and don't have any problems.
