Firefox 4- Flash not working

I am using firefox 4, and having problems with the flash plugin. Youtube works fine, but other websites with embedded flash objects (including youtube imbedded videos like youtubedoubler etc) do not work. The audio plays, but no video is visible.

I have tried to disable ad block plus and even started firefox without addons. I have uninstalled flash and re-installed, i have checked that there were no other versions of flash installed. I am using windows xp and have tried to disable the firewall to no avail. Also, this problem did not exist in the previous version 3.6 of firefox, and only started when i updated.

I would appreciate any suggestions to fix this.

Well, as nobody else has replied, perhaps this will help a few of you, though my issue sounds a bit different. Since Monday, at least both Flash and pdf docs stopped working in FF4 on my XP PC. I finally figured out was due to an update to Tile Tabs: v4.8. New update fixes it, currently held up from official release by Mozilla review:
