At least on my Tivo, each Sunday's broadcast of the Giro is not getting completely distinct guide data, so my Cycling Wishlist won't get all the coverage on it's own. (I.e. it thinks the coverage for 5/14 and 5/21 are the same as what was on 5/7). Check your To-Do lists; there's a repeat showing Monday afternoons if you miss the Sunday broadcast.
