IE 9 Video Problem

I have the current edition of IE9 but can't view any video's on certain web sites. MSN.com is the worst. The video box opens but nothing plays. I just get a blank screen. I can view video's on MSNBC and other web sites with no problems. If I go to MSN.com using Google Chrome Browser the video's open and play.

Why doesn't IE9 work only on certain web sites. You would think IE9 would work on Microsoft's own web site but I guess that is asking too much of Microsoft.

Click the tools or the gear button. Then click internet options. The first box should read "use software rendering instead of GPU rendering". Uncheck that option and try again.
