I went to DVD-only. Partly it was the occasionally crappy streaming experience for my own viewing (most of my machines run Ubuntu; I've a dedicated Win7 laptop that is perhaps underpowered for Netflix streaming). Too much pausing and image freezing while sound continued.

The biggest streaming issue was that I often watch movies with subtitles because a friend is hard of hearing. Subtitles were a grossly unreliable feature; they would appear at odd times, often in a big rush, making them useless.

(This when watching a movie via the Wii.)
