I've been a cord-cutter for many years now. After Netflix streaming arrived on the Roku, I found that my family and I watched it almost exclusively. The only things we watch on network/cable television is the local news, the Green Bay Packers, and a few network shows like The Big Bang Theory which hasn't come to Netflix streaming yet.
Using an inexpensive over-the-air antenna, I've been able to watch the Packers, and Sheldon Cooper and the gang in glorious digital HD TV - all for free and it works great!
And when it's time to let the dog out or grab a snack, I have to wait for a commercial like in olden times. And about those commercials - they seem to go on forever! What's been missing for me is time-shifting - the ability to pause live TV, to record it for later viewing, and of course, skipping commercials.
I've played around with a few different solutions over the years and finally settled in on the Tablo DVR. It sits in a hidden corner of our home and it's connected to our WiFi network. I gave it an antenna, a portable USB hard drive, and installed the Tablo app on our Roku.
Now from the comfort of my couch, I have full DVR functionality for broadcast television. I can watch live TV and record my favorite shows for later viewing. During football season, I can pause the action and grab a beer without missing a single play!
As with any Internet connected device, please install your Tablo securely.
The excellent How Tablo Works page is a great place to further explain the technology and how to set one up for yourself. Have fun and enjoy!
