This app should come bundled with the Apple TV. It feels like the "missing piece" of my home theater setup.
PS: I should add, my Plex recordings are janky too, so it's probably a ghost in my setup, but holy moly I've tried troubleshooting this thing and still can't nail it. You'll probably have better luck.
Saving us thousands a year. Live TV is flawless, the DVR has been rock solid, commercial skip is better than any I've used in the last 10 years, whole home solution lets me start watching in one room and pick it up where you left off in another. This was the third solution I tried and is miles ahead of the competition. AppleTV is a must, which is perfect for me, but if that doesn't fit your needs keep looking.
Have been using ore or less since day 1 and was a UK private beta tester for DVR. Now I have one box and one remote for my tv, music, movies, photos and apps.
It requires some hardware: an antenna, a network tunner from HDHomeRun and an NAS for the DVR server.
