Did you do a clean install of Lion? If so, you will have to download Sliverlight and install it. It's not automatically on there since it's a MS product.It's not working for me on Lion. Any suggestions? It says "plugin failure" when trying to stream on Netflix ever since I installed Lion.
I'm not sure if this is related, but when attempting to watch an online Silverlight video, the plugin crashed under Chrome, but worked in Safari.Netflix is working fine here with Silverlight 4.
It works in both Chrome and Safari.
I just downloaded OS X Lion on Friday and my Netflix wouldn't stream since then. I was so frustrated getting that "plug-in failure". The plug-in download works just fine for my Safari 5.
