No problem, it offered it on my last video upload and I selected it, felt dreadful after watching it!
You might be able to fix it if you go to the following;
Log into youtube
Go to 'video manager'
find the video you want to fix and click on 'edit'
Click on 'Enhancements' in the dark grey toobalr
a 'stabilise' button should be on the right hand side of the page, you may be able to switch it off here.
Hope that is of help!
