ok let's reset.
my response was simply direct with no reason to mix words or hem-haw around.
You can process it however that's your prerogative but I wouldn't sweat it....I saw "yea guys why no straight answer on the forum everything is
vague" and decided if im going to spend 20 minutes typing a response you'll walk away from it perfectly clear, no bad intentions. As too your issue - if you can d/l kodi then forget the firewall, a/v or anything else, shift the focus to the firestick. I believe there are programs, add ons or running tasks causing you a conflict.
your problems begin after kodi is loaded. if it were an android box I would delete EVERYTHING and only install kodi.......no add ons....nothing!
I expect your accomplishing the same when you do the factory reset so let's say
1- you reset the firestick with nothing "foreign" but kodi on it.
2- your at the main splash screen looking at the pretty blue confluence background....you see music, programs, video ...etc etc .
3- Start selecting something like 'system' or video as if your navigating into a category.......there is nothing there because it's a fresh install of kodi but the act of navigation usually initiates default downloads to start....
url resolver 'has been updated'........
'python handler has been updated'......there should be at least 60 seconds of this going on before it stops with all the basic updates. this is a great yet normal and expected occurrence....I'd think something is up if you don't see that happening. ill assume it did that.
now you have a firestick with no video add ons enabled but the elements to facilitate basic functionality are in place.
I myself would only install the 1 add on im trying to get to work so I don't have to wonder down the line if something else is causing me an issue.
I wouldn't install a guide or anything just enable pvr stalker, configure it and install 1 video add on to test it. until you get it going there is no need for anything else and it keeps what you have to troubleshoot to a minimum.
as an alternative and since I don't even use pvr stalker I personally am only going to d/l dara's modified stalker because you can easily configure and test it with little or no trouble, seeing your iptv service work will give you the confidence and push you'll need to take on pvr stalker. The trick now is to get all this done b4 that stick shows you the thermometer indicating it's too hot which pops up about 45 minutes after heavy programming, no biggie.
