Can you get the local channels with Roku? Do you know anything about TV buddy advertised on the Internet? Also I heard there is a support group called how can I get unplugged or something like that. Any information on that?

Although I've had Kodi for a few years I rarely use it. The app servers are not well supported anymore and quality is pretty poor. Troypoint is a good source for current and popular apps, along with information on downloading some of the apps that may appeal to you. You can subscribe to his emails.
If you have the "Downloader" app installed it's quite easy to add new apps. As VPN's are concerned, they are recommended for hiding your IP address and viewing preferences but can and do slow some streaming. Some of the apps I currently use and work well are, Cinema...TV Zion...Cyberflix....BeeTV and Catmouse.
