Disney, as usual, is the idiotic one in this case. Amazon admitted fault and gave a large credit. The OP should just torrent the movie if it really was interfering with his plans (although ignoring Disney is a better choice). While my kids (5 & 7) are content to use Netflix and Amazon most of the time[1], they know a full download is only a quick search away. To them there's no real difference except a slight inconvenience.

Explaining why Netflix only shows certain shows depending on proxy status (quick colored icons in Chrome), and why sometimes they'll force a show in Spanish or Portuguese and not English, and why other times they force subtitles -- it comes off as insane.

1: My main gripe with Netflix is the lack of parental controls. I'd love to be able to stupid kids show. I'd prefer them watching 16+ rated movies with good plot than some of the junk that's churned out for "kids". That and the fact that rendering quality/control is sub-par.
