On my friends MBP every time he starts a Netflix "Watch Instantly" movie Safari shuts down (unexpectaly quits), then when he goes back and trys the movie again it works !... This happens every thime he wants to watch something on Netflix "Watch Instantly"

Any ideas on how to solve this ?

Thanks.

What version of Safari is he using? Netflix recommends Safari 3 at the least. He can also try Firefox and see if it works better.

Works a lot better for me with Firefox.

I don't have any problems using Netflix streaming with Safari. Try doing a Reset Safari.

When it quits, do you get a crash warning with an option to report to Apple? If so, post the crash log here and send the report to Apple too.

Thanks a lot for the replies.

I'll let him know your suggestions.

I was having this same problem – both Firefox and Safari were crashing when I went to watch any movie via Netflix Watch Instantly.

It turns out the the problem was my Silverlight plugin – it was crashing.

Here's the fix:
1) Go to Home : The Official Microsoft Silverlight Site. This will crash your browser. (You can skip this step, but it's kind of a nice verification that the Silverlight plugin is your problem.)
2) Delete /Library/Internet Plug-Ins/Silverlight.plugin
3) Go to Home : The Official Microsoft Silverlight Site (it shouldn't crash this time) and re-install the plugin.
