Although last we checked, our Windows Phone Netflix app doesn't currently have the ability to add DVDs to our queue (was it ever there in earlier versions?), we now know that the feature won't be added anytime soon nor for the Xbox 360 either.
Netflix announced yesterday that they're removing "add DVD to queue" for all streaming devices, meaning you'll only be able to add that non-streaming title via their website. They give reasons for doing so, but we can't help but think we're going to forget to add that DVD when we get home later (or we can fire our browser we suppose, but it starts to feel redundant):
We’re removing the “Add to DVD Queue” option from streaming devices. We’re doing this so we can concentrate on offering you the titles that are available to watch instantly. Further, providing the option to add a DVD to your Queue from a streaming device complicates the instant watching experience and ties up resources that are better used to improve the overall streaming functionality.
We could say this would be a great time for a developer to make a Netflix Queue manager app, similar to what is found on Android, so long as it's just not another Mobile IE wrapper app.
