I recently moved back to using Kodi, after everything stopped working I also went with IPTV and a similar service to Vader, but didn't hear about that specific one, Vader.. i will check it out.
Some people that ask me for help with their Kodi setups often don't got anything in their pockets to pay for anything so I end up finding solutions for their cheap demands. There's new add-ons that are working just as well as they used to with In theater stuff as well, but for sure it takes more time setting up.
I was able to find a lot of the new updated stuff and tutorials on here:
Search Results for “Kodi” – Page 2 – VPNPick.com - simply search Kodi and all the tutorials come up. There's stuff for NFL, MMA, Sports in general and all the recent addons that work for this year.
