I have owned a Tablo DVR (quad tuner with lifetime guide subscription) for over four years. The model number is SPVR4-0 1-NA. I was going to cut my cord with Directv. At the moment I’m glad that I didn’t because I’m having trouble with the Tablo. It won’t play on my iPad or my Amazon Fire TV. Fortunately it still works on my Roku tv and my Roku express stick.
