Yeah, couldn't find that info. I just signed up for a beta invite, but I might hold off until they come out with a PS3 or Roku app so I can watch it on my tv. Maybe by the time those apps become available there will be a decent consensus on the service whether it's good or not.
I haven't even used my streaming netflix in about 2 months, but I have rented several movies from RedBox, so it makes sense for me. I might just cancel netflix for a couple of months and trying RedBox Instant.
I wonder if any companies signed exclusive contracts with Netflix or if they have the rights to offer the same titles to RedBox as well. I'll try to keep this thread updated as I play around with RedBox.
