Safari stop playing embedded youtube videos
I am having trouble with Safari 4.0.5 (6531.22.7) which suddenly refuse to play embedded youtube videos. Safari show the video in a web page but when played the youtube default play display "an error occurred, please try again." and Safari display in the status bar "one error in opening the page, for more information, choose Window->Activity". Now when I look in the activity window it show "forbidden" beside the video file.
Strangely I can play the same video from the youtube main page without any errors.
I have already done the following:
- checked permissions with Disk Utility.
- Reset Safari
- Empty caches
- Removed com.apple.Safari.plist
- Uninstalled, re-Installed Flash plug-in
but the problem still persist. Help in resolving will be highly appreciated.
