Get tivo stream 4k on Amazon for $40 and use tivimate. That's your best option imo.
Quvu is ok. It is stable and gets the job done. Works fine with my Samsung.
For samsung tv u can use Duplex (dying tho) Setiptv Nanomid
Duplex
Use setiptv on samsung
There is no good app for Samsung. Some people recommend Clouddy, but even that is pretty bad compared to the android apps. I recommend that you get a cheap android box or firestick and use that instead with apps like Tivimate or Smarters.
