Cutting the cable, lets talk options and media setups

I had no idea that Amazon had canned the fire recast. I was just advising someone to buy one because mine works great but when I went to send them a link, there is none to be found.

“We are constantly evaluating our product and service offerings to best serve the evolving needs of our customers,” an Amazon spokesperson told TechHive. “Many of the features offered by the Recast are now available through other apps on Fire TV, and we are focusing our efforts and resources on other Fire TV devices and services that provide great value to our customers.”
I would like to know how? How can I record over air and then play it to any of my amazon products because that is literally all the thing did.
