In the playstore it says it's not compatible when I browse the app. I side loaded it and I noticed that sometimes the app crashes and also when playing a video, the status bar shows even though it's in full screen.
I like the concept of DVR but I would not pay for it unless it gets polished and full support is added for Android TV
I haven't used that app, but Shield has a DVR built in, although it may only show up if you have a USB or network tuner. It just says Live Channels .
