I am a Quickflix subscriber. I pay $10 a month and get access to a library of movies and TV shows. I install the Quickflix app on my Android phone and cast it to my television using the chrome cast, which you can purchase from Dick Smith or JB Hi Fi for $50.
I think Quickflix is great. I am watching the Sopranos and Boardwalk Empire. I am watching early episodes. That gets to the main problem with Quickflix. The library of movies and TV shows is not very comprehensive and you mainly have to watch old movies and TV shows if you don't want to pay extra. Most content cost extra money on top of your support subscription.
I also have Google Play Movies and TV on my phone and I can also cast to my TV via Chromecast with it. I have noticed that Google has many features that Quickflix does not, mainly the ability to remember at which point of a movie you were at, the ability to download video to your device so you can watch it offline, and the ability to purchase content in HD. Google Play is simply a more polished and better product. However, Google Play does not have a $10 per month subscription. It is all pay per view. There are many shows on Quickflix that are free with the subscription that cost about $40 per season on Google Play.
