Streaming TV alternatives

[HAULN-SS]

Anyone here using Streaming TV? I use netflix, and it seems to work OK, but I dont think the service is as good for some other providers. My Internet is just barely able to keep up wtih netflix being in 720p, which is fine, and if it occasionally has to, it will re-buffer temporarily at a lower resolution, but it still keeps going.

It seems like some of the other providers out there dont have their service set up the same way. For example, Vudu will stream for a second, and if it has to re-buffer, completely drops the stream until it downloads more content in the full resolution. Well, this sucks.

Are there any services out there that let you pre-buffer larger amounts of content so the streaming isnt interrupted, or download the entire content for viewing ahead of time? I dont mind if i have to wait on the initial download, as long as the content plays smoother. It seems like Zune from xbox is the only thing that will let me buy a movie or something and it stores the content on the HDD if I want to view it later.
