ISSUE-9: suggest closing

http://www.w3.org/html/wg/tracker/issues/9

This issue has seen no action since it was raised. I think it is too  
late to add media sync to HTML5 at this point, and it does not appear  
to be a topic that has captured wide interest.

I suggest we close this issue, and consider media sync for the next  
version of HTML.

Regards,
Maciej
