I've had the Silicondust HD HomeRun Prime CableCard device for most of a year now and it works great, both on Win7 and Win8 using WMC. I live in SW PDX in sight of the Sylvan antennas and had been using OTA for the most part, along with Limited Basic cable. I got the 1-year upgrade deal to Digital Starter with HD, got the cable card (had to pick it up) and called to activate. All went well except for one extended problem: I couldn't get most of the HD channels. After many hours on the phone with tech support, and a few days, they finally sent a truck to my house. The service guy found a legacy notch filter on my line at the pole (which, by the way, tech support assured me over the phone that these devices were all removed). Once finally removed, all channels registered and I'm a happy camper. Love that I can watch and record from any PC in the house (including the living room media center), share tuners and recordings among them all over the network, and have virtually unlimited storage for recordings.
