When trying to play SOME YouTube movies, I get an error message that says: "an error occurred, please try again later" (it never plays 'later'). I checked the finder-windows-activity pane as ordered and found 6 of around twenty lines that had red "forbidden" .
What gives?

Mac OS X (10.6.6),

Carolyn, I tried playing the YouTube movie logged into my guest account and it worked perfectly.
Logged into my account, I noticed that the movie opened full screen (although it wouldn't play); whereas in the guest account version it opened within the YouTube site. I don't know if that is any help or not.
