What Luck!

My motivation to post a blog is really low now because I have been experiencing some problems with my YouTube posts. Somehow, all the video clips from YouTube (including self-made clips) are now just blank white screens. I checked other blogs with video clips from YouTube and theirs are pretty much the same as mine. Anyone knows how to resolve it? I would really hate to go back to the older posts and replace each and every one with their URL instead.
