Yourtube question

[Fox250R]

It seems most of my vids on yourtube are off with the sound..Like the sound doesnt match the video..Anybody know why this is? http://www.youtube.com/watch?v=67f6uq2nwDI

looks fine to me. There were a couple of other videos that the sound was off but they said it had something to do with a software glitch.
