Its not just for watching movies, its a DLNA server which allows you to share all your media to other devices in your house. In addition it has 3 ATSC tuners so that you can watch OTA television on any of those devices.I saw this at NAB, it looks great but it seems to me to be a lot of expense to watch Blu-ray quality movies. A second dish, another satellite receiver, cat 5 cables between receivers and monthly fees. It's just easier to keep netflix. I told them if they could get it to work with my Dish system I have now, I think they would sell more systems. They told me that it's really a niche service for extremely high end home theaters.
Just think you can enjoy all of this on things such as your Playstation 3, and TV's which are DLNA compatible without the need for additional boxes / receivers.
