If I remember correctly when the V+ was first available quite a lot of people had problems using the remote. It took some convincing to accept that it was actually a problem between the remote signal and light bulbs which had never effected our original Sammy STB.

I realise that this did not happen with your V+ but you have added a new piece of equipment which maybe is picking up on a setting on the TV. So is it not possible that there is setting on your TV which the Tivo is being effected by as Spider says?
