I'm very new to the scene (less than a week), and I'm having a bit of difficulty understanding the CCK module. My current setup is as follows: TV 1: HR34 receiver; ATT U-Verse Wireless Router two feet away from HR34 (but not connected in any way). TV 2: H25 receiver. TV 3: H25 receiver. All of the TV's are in communication with each other. I can watch shared DVR content on any of the three TVs. I'm guessing this is what is commonly referred to as MRV (a/k/a multi-room viewing). So, why do I need the CCK? Can't I just hardline the HR34 into the router and enjoy the On Demand stuff on all TVs since they are all in communication with one another? Also, despite that the CCK is on its way to me in the mail, and I'm sure the instructions will better inform me, I thought I'd ask: How do you connect it? Do you hardline an ethernet cable from the modem to the CCK and then another cable from the CCK to the HR34?
