How Can I watch PPV fights on Android TV?

I recently got an Android TV and went straight to putting Stremio + RDB + Torrentio on it. I've really been liking it but I don't have a way of getting quality PPV events. I don't mind coughing up some money for a good IPTV (if necessary) but I just want reliable HD streams with little to no buffering. I know about the Web Video Caster app which I used to stream from my phone browser but those websites crash/buffer a lot and can be unreliable. Can anyone help me out?
