Lastest update please.....

[kenkali]

I wanna start with comcast cable dig box.. I read lots in the forum but heard that they keep changing the keys weekly so pointless of mod the UID..ect.
Can someone please point me the direction where to get start? Do I need to sub? and what boxes are do-able?
I'd been using sat, and never had cable digital service.. not familiar.. Thanks in advance.
