StoptheCap reported that Netflix was enforcing a single stream per account and had an error screen to back it up (and a bunch of sites picked up the story without verifying it with Netflix), but Steve Swasey, Netflix's VP, Corporate Communications, told HackingNetflix:
No Netflix member is limited to less than two concurrent streams. A few Netflix members have heard differently from us, which is an error that we are correcting.
I was able to stream on 3 different devices (2 PC's and the Roku) simultaneously last night on a $7.99 per month streaming-only account, so I'm wondering if there is a bug in the Netflix code that determines how many streams you can have.
Here's the Netflix streaming policy from the Netflix Help System:
Q: Can I watch movies instantly on more than one PC or Netflix-ready device?
A: Some membership plans allow you to watch simultaneously on more than one personal computer or Netflix-ready device. If you are on the Unlimited Streaming plan, the Unlimited Streaming + 1 DVD out-at-a-time plan or a limited streaming plan, you may watch only one device at a time.If you are on the Unlimited Streaming + 2 DVDs out-at-a-time plan, you may watch on up to two devices at a time. Members on the Unlimited Streaming + 3 DVDs out-at-a-time plan may watch on up to three devices at a time. The maximum is four devices at a time -- available for members on the Unlimited Streaming + 4-or greater DVDs out-at-a-time plan.
Are you able to get 2 or more streams on your account?
Thanks to Phil, Art, Lamontrey, Jeff, Desiree, Anthony, FearNo1, and everyone else for sending this in.
