netStream.bufferTime error

HiI am working with few FVL files I am streaming them form the server. If I use the buffertime property to buffer the first 10 sec and then once thats done I am pausing the stream and resuming it on the click of a button.Now what happens is that when I press play it fast forwards the first few seconds and then starts to play.It is a very annoying error can anyone please help me with this?ThanksAd
