I've been using spcentral on a month by month basis for a while and it's suited me perfectly. I'm only really interested in sports and will be using either through kodi or just vlc on my windows pc.
My sub is up and for some reason I'm not able to send payment to their account. I need something sorted asap for UFC tonight. Any suggestions?
If it's sports you want, check out smoothstreamstv
There are lots of options, but you've sorta limited yourself with the devices you have chosen.
For generic tv other than sports, consider Torula
If you're looking for a true cable-company like experience, you won't get that from Kodi. If you decide to go this route, consider checking out the set top box video reviews over at /r/iptvgta in the stickies
