So far I haven't been that impressed with any of the Netflix clients...although come to think of it I haven't tried the built-in Playstation one yet. But I've had the disc one crash my Playstation, the built in one crash my Xbox and my Tivo.
I like the Tivo one's interface the best, except my Tivo's expensive and theoretically could get corrupted or something from crashing it, so I never, ever use that one. When my consoles crash, well no big deal.
I pay for the cheapest DSL I can get and they all seem to work as far as that goes.
