I have fire stick and do not have a smart TV ( the one using the stick)...works great as it does in any other TV with an HDMI port.

A smart TV makes the TV internet capable so you can access sites like Hulu, Netflix, YouTube etc. without an additional device. Uses wifi directly rather than through the stick...or...uses the stick if input is changed

The TV in SXM is not the issue...the issue is Amazon seeing a International wifi IP and limiting what is available...I'm looking forward to giving it a go in 12 days
