I have just received and self installed a new Tivo box, offered free as an upgrade to my old HD box. I have one Tivo box already so familiar with all functions.
The whole setup process went very smoothly indeed and using the automated activation line the box was fully setup in less than 20 minutes.
One thing did strike as a bit of an oversight. In the blue pamphlet entitled 'Get Set,give us a call.' It goes through the procedure for disconnecting/reconnecting cables etc but nowhere in this guide does it mention swapping over the smart card????
Not sure if these self install packs are sent out to everyone but I know one or two people who would have chucked out the old box together with the smart card.
