Got it!!!!
When I called the special number I spoke to a lady from Eastern Europe who was very friendly but seemed to be desperately in need of some training. She tried to charge me for keeping my two V+ boxes. When I told her to forget the Tivo (brave man me) she went off for 15 minutes while I held on listening to some garbled information about what seemed to be advertising "Talk Talk", very strange. When she eventually returned it was to apologise for the delay and to tell me I can keep the two V+ boxes free of charge. I am using the Tivo to replace a Samsung V HD box.
Installation on Friday morning April 15th.
Thanks to DF for the information and despite earlier comments on this forum he was spot on with his predictions. As he stated they have sent out emails beginning April 11th.
Three Cheers for DF!
