I'm in the same boat. TW customer, tivo premier box. I just ordered ESPN 3D (for the 2nd time). When I get home tonight we'll see if I get the channel. I doubt it. Then I'll have to try and figure out what the trouble is, with no help from Time Warner (they do as little as possible to help tivo customers) and no help from tivo (who, surprisingly, seems as ignorant about these issues as anyone else). I'm very frustrated that this is the state of play in March 2011, a year after 3 D sets started being sold in volume, but there it is.
