I agree with all that has been said before. Before reading these reviews I thought the problem with my unit freezing and needing to constantly be rebooted was that it was a rare lemon. I have had a Samsung dvr for years and have had flawless service out of it, and it is a dream to operate. I leased this second DVR for other household members and found it impossible to program and quite clumsy in operation. Why do I need to push the guide button twice just to see the channel guide? Why is it so slow in opening and changing operations? I canceled the lease, but Directv in it's usual incompetency has not bothered to pick it up. I offered to drive 40 miles to deliver it to a retail store and they refused because it had to sent by FedEX.
