Yesterday I was looking for a way to see "Argo" and saw that I could eaither purchases it through the Amazon menu on my Tivo HD for $19.99 or "rent" it for $4.99, which is a file that you can download that deletes itself after a day or two. That evening my wife & I went back to set up this download, but only the $19.99 purchase option appeared. This morning went on again, saw the $4.99 rental option and selected it. The TiVo had not yet been connected to Amazon account, so I started setting it up, but did not have the correct Amazon ID & password (my wife manages the Amazon account). When she got up later, the $4.99 rental option dissappeared again and we only see the $19.99 purchase option. Can someone tell me what the heck is going on?
