Wez, can you still repro this?  If not please close.  If so please punt back to Untriaged (and send feedback w/ logs).

Yes, it still repros at @ 50.0.2661.32

Repro steps:
1. Load netflix.com and start playing a video.
2. Start casting to a device.
3. Cancelling casting.
4. Start casting to the device again.

At #4 the Netflix app will re-load on the Chromecast device, but won't play the video.

Vadim, can you take a look?

Dropping milestone unless we can confirm it's an MR issue.

Wez, does this still repro?  We've had some reports of bugs with NF (on their end) but this may now be resolved.

Re #9: I tried last night w/ the extension, and was able to repro the issue once:
- The video then played for ~30 seconds.
- I tried stopping the first Cast attempt and re-trying.
- This time it worked, but the video started from the beginning, rather than from ~30 seconds in.

This was on a Windows device, running the old extension, though - which would support the idea that it's not MR nor ChromeOS specific.

I strongly suspect this is a NF issue, based on similar reports we've seen.  Wez if you can reproduce similar behavior on other sites though, please let me know.  cc-ing petem@ for follow-up with NF.
