Just went and got this all signed up for and sent the first video to my TiVo. Hopefully when I get home this evening, I will have Little Miss Sunshine sitting on my TiVo waiting for me to watch. Super easy to get this set up and one click downloading to order, so the interface is pretty easy. It would be nice to be able to make a queue of some sort though.
Pretty good terms for a rental too. You get 30 days to watch it, but once you have started it, you must watch it within 24 hours. Also, if you sign up now, you get $15 in videos for free.
Biggest disappointment so far? This isn't something that I could just do as part of my Netflix subscription.
More once I see the other side.
