Here in the Chicago suburbs, we had two options for whole-home DVR services. We initially went with WOW Ultra TV, and after about 4 months, we switched to DirecTV's HR34 Genie system. (Neither Verizon FIOS nor AT&T UVerse were available in our area, so we can't review those. I haven't used Dish's Hopper, either. This is a straight compare/contrast review of WOW vs. DirecTV.) Both Ultra TV and Genie have their plusses and minuses. Both offer 1080p output, but that's primarily for the menus, as most TV content is provided at lower resolutions. Both systems have a similar design architecture - a central hub, with multiple tuners and a large hard drive, recording and storing all TV shows, and distributing them to televisions around the house upon request. Both systems also bring a number of "add-on" apps and have ways of accessing "on demand" content. We've had each system for enough time to really put them through
