ActionScript 3.0 :: Avoiding Delay In Flv Player While Switching To Other File

I am working on a project where basically dealing with flv player and videos, am trying to play multiple flv videos of a 3d human character who is speaking out a number like 3550.Here we are using multiple video files and joining them like videos where character says 3 then 1000 then  5 then 50.The issue here is after every video there is a fraction of second where the character is disappearing from the stage which we can't afford because all the numbers have to be played at once to show it as one single digit.I know that this is not a script error but this is how the flv player plays, after one file there will be a delay to play the other.What can I do to achieve  my goal and also can how we can download all the required flv files from  server to client machine to avoid a streaming delay (All the videos are of 50 to 60 kb files).
