Seek Immediately

Created by: TheHedge

Is there a way to immediately seek to a a location within the media source upon initial load?

I'm trying to essentially leave a bookmark of where I last played and then, when the attachSource() is invoked, seek immediately to that position , starting playback from there.

All that I have tried, either via goigng through the streamController and even the underlying HTML5 video has been frutiless. Playback is always starting back up at "location 0"
