hi all, I need to develop a seek function in the video player.
the user will be able to drag the progress bar going backwards or forward in 
the video timeline.

I found this article:
http://www.flashcomguru.com/index.cfm/2006/5/10/flvkeyframes
http://polygeek.com/211_flex_seeking-in-flash-video

it's very good and helpful but still I have some doubts.

I know that the seek function is affected by the keyframe number when the flv 
was created, as shwon in the article.

my questions are:

- what's the logic behind the seek bar to enable the video to keep showing the 
video keyframes when draging?

why if I start to drag, stop in any postion (already loaded) and don't release 
the mouse the video keep shaking?

the ability of drag the video timeline "head" to a unloaded position and the 
video stop loading the previous content and start again from the position you 
dragged the head, I'll need a flash streaming server.

if the video is hosted in a non-streaming server the "normal" behavior when you 
drag the head to a unloaded position is that the player will wait the video 
loads until that moment and once loaded it will start playing, is that correct?



thanks for your help.
rodrigo.
