Firs TV Stick Kodi - Slow motion, lag, stuttering Live TV

So I'm trying to watch some live NFL games on my stick that aren't on TV in my area, but they all seem to lag, stutter, go in slow motion either right when I start the stream or after a minute or two. I'm using sports devil, phoenix, vdubt, etc... Basically same with all of them.

Is there something I can do to resolve this?

Kodi on AFTV. Catagorize Android Apps?

I am gonna root my AFTV and eventually have it boot straight to Kodi. Is there a way to have separate folders or catagorize when I go to the Android apps section within Kodi, so all Android apps aren't all listed together?
