The first two years I had my cable card with the HD Prime, I received all channels, including HBO just fine, but it did take trying three different cable cards. Then all of a sudden a bunch of channels like Comedy Network and other stopped working. So I got a couple of other cards and everything works except HBO and Encore. I blame Comcast. But even without HBO, which means I rent a Comcast DVR anyway, I still prefer this device over the Comcast DVR. The reason is more record channels, three instead of two, and basically unlimited storage space. I currently have a 1TB, 3TB, 3TB and my current 4TB external as storage space. So I can save a ton of shows for literally years and years. Given the future of WMC, I would probably be more leery about purchasing now, but I still might do it for this price. If you can get Comcast to fully initialize it so it receives all the channels, including HBO, it can literally pay for itself in a few months with no more DVR rentals. Mine paid for itself years ago, so even now that I choose to rent a DVR and don't get the savings every month, I still prefer this.
