Maybe the Adobe Flash software (needed for flash video) got corrupted. What browser do you use? Only Safari? What version?
My suggestions:
- I assume you already restarted your Mac recently, otherwise try this first.
- Testing the sites from another browser, like Firefox. If needed, download is available at Mozilla.com. If this works properly, then something is wrong with Safari.
- Reinstalling/updating Flash (download from Adobe.com of Macupdate.com)
Please let us know if these suggestions work, or not.
