I bunch of people gave you fair answers already. Next thing you have to do is understand.. Asterruk is Asterruk! There's no direct replacement for what and how it works. This is why they are still in business. If you want to replicate it and legally, you'll probably end spending more cash, time to setup, more stress and all without that reliability and ease of use associated with Asterruk's service.

Now, based on your request and responses.. You do not need another mere casting device.. What you need is a proper media player that can be somewhat molded and used for live TV, YouTube and Netflix. But most importantly, the live TV. Go read the page one throughly and the last 20 or so pages.. There's a wealth of information already available. Just read and digest. You'll either need some more help deciding between 2 or 3 devices...or you'll already know which to get.

If you feel the above is too much work for you? Then I'm sorry to inform you that the life of a cord cutter is not for you and you should stick to paying Asterruk to sort things out for you.
