YouTube videos won't play on Safari 5.1.3
Many youtube video on Safari 5.1.3 don't play just show a black screen. I open the same link in Firefox 10.0.2 and the videos play. I read this may be caused by caused by downloading a bad torrent(s)?
What can I do to fix this?
Thanks for all helpful suggestions.
