Looks like it might. Hard on the heals of my excellent first impressions of IE9 RC I had a little bit of a jarring return to earth in the matter of installing Beta/RC versions of products. I started Windows Media Center and activated Netflix so I could watch another espisode of my current obsession, “Rescue Me” with Denis Leary, and this is what happened after I clicked “Play” and the familiar red screen appeared:
[Update] No work-around, but some additional information. I spoke to Netflix customer support, and they hadn’t heard anything about this issue. The woman on the other end of the call stressed that they are not compatible with IE9 yet, and I guess this proves the point. I uninstalled the IE9 RC Windows Update and after a restart Netflix streaming functionality was restored. So this is a heads-up for people who use Netflix in Media Center, and would like to try IE9 RC.
[Update] The problem was confirmed by poster “Dark Shroud” on the Anandtech forums. The same poster did note that he was able to get Netflix working in the browser, so that will have to be the fallback option for WMC users who want to run the latest Microsoft browser, at least until Netflix releases an update to their player script for Media Center.
[Update 2-24] Poster Marc W. sent a link to a Microsoft KB that supposedly fixed the issue, but didn’t due to a typo. Marc commented again today that it has been updated with the correct registry value, and that it now works. I haven’t had time to test this myself, but give it a go if you’re yearning to use IE9RC and watch Netflix in Media Center: http://support.microsoft.com/kb/2512239.
