Hi all, I've spent quite a while searching for the answer to this but no success so I'll pose my question.
I'm planning on upgrading my S2 DTivo boxes soon, to 1- HR34 and 2- THR22s.
DTV CSR's tell me that I have to order and have CCK installed.
I do not need/want MRV, VOD, PPV.
I may want to use Directv2pc.
Do I really need to have CCK installed?
Can I setup Directv2pc using the ethernet ports on the DVR's instead?
In the event the installer does insist on installing CCK, can I "wall off" the DVR's from accessing the public internet without causing any problems?
In order for Multi Room Viewing (MRV) to work, the boxes must be a compatible type and networked together (TiVo's are not compatible with MRV). You can network the boxes together with standard Ethernet cable. SWM users can also network the boxes together over the same RG-6 that delivers the Satellite signal. DirecTV's policy is that you must network via the Coax before they will turn on MRV (it's possible, but not easy, to get around this). As a general rule, a receiver can be networked with an Ethernet cable, or over the Coax, but not both (the HR34 is an exception)
The Cinema Connection Kit (CCK) acts as a bridge between the Coax network and your home's regular Ethernet. This connection allows boxes with Coax networking to connect out over the Internet. The box needs the Internet connection in order for Video On Demand (VOD) to work.
If you have the Internet Connection, you don't need a full time phone line in order for pay per view (PPV) to work.
If you just want VOD without MRV, you can hook all your boxes up with Ethernet, and skip the networking over Coax. If this is the case you don't need the CCK.
The HR34 can act like a CCK. If your receivers are all networked via Coax, you can plug your home Ethernet into your HR34, and it will bridge the ethernet and Coax together. If you choose this option, you don't need a CCK.
There are at least two different pieces of equipment called a CCK. One requires a wired connection, and one will connect to your home network over Wi-Fi. The Wi-Fi version is much bigger, and takes up more space. It is also easier to install as it has a coax pass through (the wired-only CCK requires a dedicated Coax drop).
The above is a simplification. There are exceptions, but this is generally how it works.
The bottom line is that if you have an HR34, you don't need a CCK (although DirecTV may require you to buy one). Even if you have an HR34, if it isn't convenient to run an Ethernet cable to it, you may want a CCK.
