I am on version 5.06 of the IPB. I noticed that when I added YT videos with the new version into a post it goes automaticly to fullscreen. On older video's in the posts I noticed that they are not diplayed on fullscreen. Is there a way I can fix this or is there only the way to edit each single post with the older video's ?

Thanks for the help in forward
