I love Netflix streaming. I like to browse the selections and pick out movies I would not bother renting on DVD. If I don't like it, I move onto the next without feeling I've wasted my money. Normally, the movies I watch wouldn't require 5.1 audio anyway, so that's never bothered me much. However, I still think it should become standard if the movie originally has it.
