I was at my neighbor's place who are new to DVRs and had just gotten a new comcast dvr. I was trying to show them the features etc, and in the process realized how good the HR-20 100 that I have has been compared to the comcast dvr. That dvr was so sluggish, and the interface was so kludgy. I have had 2 HR-20's since September 2007. One of them has already filled 1 external drive 750G, and has 15% free on its 2nd 1 TB drive. Just wanted to express that you don't realize how good you have it till you try something else that isn't. p.s: I know people have had issues with the directv hardware as well, but I have been lucky to not have had any issues.
