Comcast Digital Cable Box Tuner differences?
Answers: A box purchased off of eBay will not work on your cable near Comcast. Each box that is surrounded by Comcast's network, have specific encryption codes loaded in their headend computer. These encryption codes are generate by the set top manufacturer and loaded merely on the headend computer that the box is going to be used on. Cable companies will not request new encryption codes from the manufacture for a box that was purchased out of flea market.
Secondly, Comcast might not have an OS code surrounded by their headend computer that matches the build and rev of your box. Without that code or encryption key, the box that you purchase off of eBay merely makes a well-mannered doorstop or boat anchor.

These tentative boxes will have separable collateral that you will have to rent from the cable company. The separable surety will be a cable a cable card that you insert into your purchased box.
