There is nothing out there streaming in 1080p. It would eat up too much bandwidth. Even running Netflix in the best solution, it can eat up 1 to 2.3 gb per hour for HD, depending on the movie that you are watching, and you have no one running torrents, or downloads on your LAN.
I run netflix from a roku & from a Sony blu-ray, and overall, both have the same quality for netflix, since again it is a 720p stream, and even though both are set for 1080p, it will never achieve that through this service. There are some out there that claim 1080p ondemand, but you have to have the pipe to allow, and again depends on the movie, since none are out there filmed in 1080p to begin with.
