Hi there, hopefully someone can help me work out this problem I’ve been having for the past two days!! 
I have a built my own AS3 Flash video player and the ‘scrubber’ bar appears to be causing an error message when dragged too far ahead (I assume because it’s dragging ahead to a part of the video which has yet to fully load).
The error message I’m getting is…
Error #2044: Unhandled NetStatusEvent:. level=error, code=NetStream.Seek.InvalidTime
at VPlayer()
My VPlayer Class (which creates the video player) code is as follows…
NOTE: to find the scrubbing code look for the comment “// Handle the scrubbing through the video playback” and you’ll see that I’ve attempted to wrap the scrubbing code in a Try/Catch statement (which doesn’t seem to work as it doesn’t catch any errors so you can remove that Try/Catch statement if you feel it’s not needed)
