Just curious if anyone has tried this or knows how it would work... - Say I've ordered an Unbox movie and saved it in my MediaLibrary on Amazon.com, but I've haven't downloaded to my Tivo yet ... So one evening I'm watching TV and I decide I'd like to watch that movie tonight, and someone else in my household is using the computer. If I go to the Unbox menu on my Tivo and download from there, will I get charged a 2nd time for the movie I already own? And another hypothetical... - Say I want to order a TV episode on Unbox, but I can't remember if I've already ordered that one. If I order it on my Tivo, and it turns out it's one I already purchased it before, will Tivo give me a warning screen (i.e, "you already purchased this movie"), or will it just download it and charge me a 2nd time?
