We were wanting to be able to watch what we had on DVR on our tablets both at home and away from home. In order to do that we had to get the Direct TV Genie system with the GenieGo. This made it extremely simple to not only watch programming from our DirecTV service on our computers, tablets and smartphones, it made it so we could watch anything that was recorded on our DVR too. The system is really cool in how it works.
You do need the Internet and Wi-Fi at your house. However, if you are using tablets and other things, you probably already have that set up. You download an app onto your devices, and you can then use the Direct TV Genie system to watch programming and your DVR stuff. Older satellite receiver boxes can get a standalone GenieGo device to hook up to the main receiver. That is what we have.
When you are home, you are watching your DVR stuff over your own network. For on-the-go viewing, you set your router to do a simple port forwarding. They have instructions on how to do this. Then you can access your DVR content from other places. At grandmas house who only has a digital antenna and local channels? Then use the system to watch your shows that are recording on your DVR from her house on your tablet, smartphone or computer.
My wife and I keep up with our favorite shows when we are traveling. We have a laptop PC with a big HD screen, and we access what is on our DVR at home through any decent Wi-Fi connection. Friends, hotels and other places we stay at almost always have decent Wi-Fi. It is really cool to be able to watch whatever is on the DVR at home no matter where we happen to be. Sometimes I set the local news to record so we can watch it while on a business trip or even when visiting for the holidays.
