    The Comcast 877 CableCARD activation number was able to successfully activate the CableCARD in the HDHR Prime 3CC on the second attempt. The HDHR Setup Utility found all three tuners. Scan shows my channel list from the card. Authorization: Success, Activation: Success, OOB Lock: Success, Signal Strength: 100%, Signal Quality: 100%

    The problem I have is stuttering on certain channels. I've tried both the gigabit wired connection and 450 Mbps Wireless-N connection. The HDHR Prime 3CC is connected via gigabit. Specific example was stuttering on Megamind on HBOHD (801). I checked the tuner signal and its 96-97% with 11-12 rate.

    Just wanted to post a solution to those who may be interested.

    The stutter was two fold: 1) 29/59 frame rate issue and 2) disk access.

    1) disable image enhancement under media in the intel drivers

    2) create an exception in microsoft security essentials for .mtv files
