Samsung DVD Players Cannot Stream Netflix

Netflix was streaming perfectly one day, and the next I got the "We cannot play this title at this time," or whatever, error. Netflix still streams perfectly on my two Macs, so it's clearly a breakdown of the Samsung device. I've tried all of the suggestions in this and other forums, but I'm not going to call some help desk in India and get a runaround from someone reading corporate b.s. off their screen.

So, I'm going to buy a Roku box and just use the 5700 to play DVDs and remind myself never to buy anything by Samsung again.
