I had the Verizon DVR for about 6 months until upgrading to the Tivo HD. Painlees install even with a tech who had never seen a cable card before. I couldn't stand the remote lag or the guide data. I could put up with the Comcast DVR, but the Verizon one is a big steaming pile of crap. Luckily I still have a lifetime Series 1 box and was eligible for MSD, otherwise I wouldn't have bought the new unit due to cost. I haven't noticed any issues, but I haven't had the box very long and am more of a casual user. I put up with close to 5 years of pixellation problems on Comcast.... so am very tolerant.
