Where to find streaming videos that don't have buffering problem like on Hulu

[any ANONYMOUS forum user]

We live in the middle of nowhere and have DSL from the only provider available. The internet speed is okay during the day, but it slows down too much in the evening. Unfortunately, that's also when we want to watch videos. Web-sites like Hulu don't allows us to watch streaming videos smoothly. They keep and keep buffering, so we end up having to buffer, watch, buffer, watch, etc.

Are there any similar sites that would enable us to buffer the entire video before we sit down to watch it?
