Seeking to a Time Code/keyframe

Hi

I am trying to set up a player which allows me to show a 20minute .flv which comprises chapters. I want to give the viewer a set of ten chapter links. When the viewer clicks on a chapter link the video should seek to the timecode/keyframe. I hvae set up the file with xmoov.php to allow manual seeking. I am just stuck with building th code to make it seek via a link.

The link will look like a button on the page.

Any pointers please?

Thanks
