Hans,

I have updated the API documentation based on your comments and the updated
patch is sent to the list. So could you please send a pull request to Mauro for 
the video timing API patch along with this documentation patch? If there are 
any minor issues, I would prefer to fix it by another patch than re-working 
this again.
