First let me state that I have been with Fios since it first became available in our neighborhood. I made the switch from threee DVRs to the nw Quantum service. Since upgrading to the new servers, response to remote key presses is slow, programs freeze, EAS errors require power off resets, using the TV to access Voice mail is useless. I have block anonymous calls, but the "UNKNOWN: calls keep coming through. Sometimes while watching a recorded show, pressing forward to ship the commercial sends the show back to the beginning of the show. Fixing that requires another power reset.
If it wasn't for the 50 capacity, and flawess picture quality, I'd consider cable.
