Here’s a quick video I put together showing how to get Safari, Opera, and Chrome working with Netflix’s instant streaming.
NOTE: If you change Chrome’s useragent in the way described, all chrome windows will have that new useragnet. This can lead to problems with some sites. I’ve only noticed Gmail not working. To fix it, remove the custom useragent, or create two seperate shortcuts to Chrome, one for Netflix and one for all other browsing.
