We support streaming on the PS4 browser, however, there are differences in PS4 models which is why you need to test your stream first by going to this page on your PS4's browser. If you are able to watch smoothly you are all set!
Alternatively you can purchase directly from the PS4 store. Please keep in mind that this purchase is powered by FITE but cannot be accessed on the FITE apps and website. It is NOT synced to your FITE account.
