Q&A: Why is the audio and video out of sync in my YouTube video?

Question by Tertium Quid: Why is the audio and video out of sync in my YouTube video?
I have Windows Live Movie Maker, the latest edition I believe. Tonight I made a video and used the “Publish on YouTube” button Movie Make now has. The video directly uploaded to YouTube. When I watched the video on YouTube the audio & video were out of sync. I went back to my computer and watched the Windows Media Audio/Visual file on my computer, and the audio and video were synched up fine. What did I do wrong? Should I NOT have used the new “Publish on YouTube” button? What steps should I follow to make sure my video and audio are synched up?Thanks.
