Problems with videos on Blogger?

There seems to be an issue with some of the videos I have posted the last few weeks so I thought I would ask whether anyone else has experienced problems viewing videos (on my blog or other blogs). When viewing the video a message "This video is temporarily unavaible" appears on the screen. I am going to look at alternatives such as putting the videos on Youtube and then linking from my posts to Youtube. In the meantime, if anyone has any suggestions or feedback, I'd appreciate it.
