Does anyone know how to fix an issue with the downloading of HD Movies from Amazon. On several occasions I have ordered a movie, the download starts, but goes VERY Slowly. After 20 minutes or so I only had 3 minutes of the movie. I rebooted and after another 20 minutes only 17 seconds of the movie! Clearly this is not "on demand". I have purchased many TV episodes using the Amazon website and sent them to the TiVo with no issues. This seems to be related to ordering movies from the TiVo itself. It's a Tivo Premiere.
