In 2013, I recommended setting up your own digital video recorder by using a mish-mash of components. It works well, but was not very user friendly. Today, with some inexpensive tools, you can have a great DVR right in your own home without much effort.
I especially like the home media-streaming tool Plex. Think of Plex as Netflix for your content. Record home movie or take tons of pictures? Toss them into Plex and watch them on the big screen. With the recent update of Plex, you can now use the HD Home Run device I suggested back in 2013 to record live TV and add it to your Plex server. There is a small subscription fee to gain access to this functionality in Plex, but if most of your TV shows air live, this may be a cheap alternative to paying for ala carte streaming services. You can check out the Plex DVR features here. Heck, if you have a modern game console (Xbox, PlayStation), you can download and use Plex from there with no need for a separate computer.
