Netflix streaming gives Error Code: S7363-1261-FFFFD000

MacBook Pro OSX Yosemite 10.10 (14A389), patched to current on all software (which may be the problem). Safari v. 8.0 (10600.1.25) with Silverlight plug-in 5.1.30514.0.

The only symptom (so far) is that Netflix refuses to play streaming video saying the device has a hardware problem. (The full error from Netflix is "Whoops, Something went wrong... Your device has a hardware issue which is preventing Premium Video Playback. Contact Apple Support for more information." And at the bottom of the window, Error Code: S7363-1261-FFFFD000.) Since nothing else seems to be affected, I'm betting on the Silverlight plug-in for Safari rather than an actual hardware problem.

Prior to installing Yosemite, I had no problem with Netflix. During the installation, I turned on File Vault. Thinking that might be causing Silverlight some heartburn, I disabled File Vault and decrypted the drive. No change.

My girlfriend has an identical MacBook Pro, running the same OS revision on the same network and is not having this problem. (This is what prompted me to turn off File Vault, since she did not turn that feature on when upgrading to Yosemite.) We have the same security software (e-Set) and the only other software differences I know of are that she does not have Pages or Keynote installed (they came with my Mac when I bought it, but when she bought hers they weren't bundling those programs into OSX). Since there was just an update to Pages, that install could have caused a conflict, though it seems unlikely. I only meniton it because it is a difference between the Macbook that works, and the one that doesn't.

Youtube and other sites using Flash don't appear to be affected, but I don't know of another site that uses Silverlight, so I can't test that. I've tried all the usual generic fixes, and so far nothing has resolved the problem. So (a) has anyone else encountered this, and (b) did you resolve it?

MacBook Pro, OS X Yosemite (10.10)

The issue is related to Safari 8's use of HTML5 over Silverlight, BUT it is only a problem for some configurations/devices. An alternative workaround to installing another browser, is to enable Develop Mode in Safari and then manually change the browser Agent to Safari 7. This will ensure Silverlight is used for the browser tab where you made the change (and only for that tab).

The downside --aside from the nuisance factor-- is that the CPU and energy benefits of HTML5 are not realized, but this would be the same situation on any browser where you are using Silverlight instead of HTML5.
