Why won't Netflix play videos on my iPad? Go to watch any video instantly.  Click on play video.  It'll say that it's preparing to load.  Then it switches to the video screen for half a second, then back to the preparing to load screen, then dumps me back to the browsing for instant videos screen.  So the video never played at all.

Any idea on how to fix this?
I managed to resolve this by changing my DNS server to Google's 8.8.8.8.  Not ideal, but it worked.  Still, any ideas why this is happening?
