I tried renting a movie using Unbox. Well, I tried to try it, anyway. The movie (1 hr. 44 min. long) took more than 10 hours to make its way onto my TiVo. (Not sure how long in all, as I ended up going to bed without watching the movie.)
My connection isn't the quickest, I know, but I do have broadband internet. I was hoping the movies would only take a couple hours at the most, so you could order a movie in the early afternoon and watch it that night. Obviously with a 10+ hour DL time that's not possible. Is it normal for it to take so long? How can I speed it up?
