Netflix authentication problem in WMC but not in browsers
I also am seeing the authentication problem with Netflix in WMC (Win 7 64bit) on our HTPC.
The same result obtains whether launching from the icon in the Movies strip in WMC start menu, launching in Boxee under WMC (never gets past "connecting to the Netflix movie server"), or launching from Internet TV Channels in TV strip in WMC. Also have the same connecting problem in Boxee standalone app.
But, Netflix works fine in IE and in Firefox (v8 and v4 respectively).
I noticed lots of updates from MS over the last couple of days.... about the time this problem started.... including a Silverlight update that makes me suspicious. Also, at some point recently, the Netflix streaming UI changed... maybe the API did as well?
Applying all the superstitious or otherwise fixes that have worked for others when this happened in 2009, 2010, etc, did not make this problem go away for me.
Hoping for a resolution for restored peace in the household.
