I have it and so far NOT impressed
We've had it less than a week and already it has been out of service 3 times. You can't rewind live TV (HELLO?!?!? The most BASIC function of a DVR), you can only pause for 15 minutes, the button to take you back a few seconds doesn't work, it's slow to respond to the remote, when rewinding or fast forwarding through commercials the auto adjust when you press play makes it IMPOSSIBLE to get to exactly where you need to be, the PIP function does not work, when scheduling a recording in the future the guide goes back to the date/time/channel you are currently on each time (making it terribly time consuming to set multiple recordings) and the interface is slower than anything you can imagine.
I'm giving to two months and if I see no improvements, I'm going back to DirecTV or possiblyt U-Verse.
