Coding Seek Bar Handle - SeekBar Component

By default you can drag the flash seekbar handle to any position till the end even when it isn’t loaded fully.What i’m trying to do is to restrict the seekbarHandle in my video to the amount it is loaded.

But because the default seekbr handle in the component is on Frame2 so i’m unable to code for it. I have set :

my_FLVPlybk.seekBar = my_seekbar;

So lets say i want to change the X position of the handle then i’ve tried various methods like my_seekbar.handle.x = 0 etc. But nothing works!

So is it possible to code the handle manually?

My second question is realted to the above. Is is possible to know the amount of seconds loaded in for the video? This would make my task much easier. As then i can code for the bufferTime manually instead of using the bufferTime property. I can’t use the default bufferTime property because it hides the seekBar handle.

Thanks!
