Why can I not play/run videos are a few sites like WSJ.com?

WSJ uses Flash videos.

Upgrade or reinstall your flash player:

If that doesn't work, then you may have a corrupt flash install. Run the flash uninstaller tool and reinstall and see if it works.

I found the problem myself. It had to do with flash player settings, Right click on video area, see local settings set to 0. Raise above 0 and it works.

Separate issue is that reports say setting above 0 allows the site to track you.
