Hi Roxysam, Cathe OnDemand should work just fine on an Amazon Fire tablet using the built-in web browser, but if you are talking about Fire TV, at the moment there does not seem to be a viable method to view it on those devices. OnDemand requires a web browser, and searching on Amazon's Fire TV app store doesn't show any available with the necessary technologies in place to support our videos. However, there do seem to be apps available that enable streaming from an Android or iOS device to the Fire TV, which could be a possibility for you to investigate.
