Integrate buffering into custom flv player/editor

Updating a custom built -but open source- FLV player and clip editor built for the Stories Matter framework with buffering/gradual loading functionality. The current player does not buffer the movie file and thus only allows to play it after the whole movie is downloaded. We have to use this player as it is custom built to be able to create/play clips (fragments) of a larger file (through timestamps) and to create/play playlists consisting of several clips. It is used in a drupal environment but syncs with an Adobe AIR application that functions a bit like iTunes. This AIR application also uses the same flv player. The player uses actionscript3 and javascript. So, only bid if you have knowledge of these languages and if you have experience with FLV player. There is not a lot of time for trial and error as the strict deadline of the project is April 15th, but the earlier the better. An example of the problem can be seen on this page: [login to view URL] The black box sits there for a couple of minutes until the full movie (audioclip in this case) is downloaded. The current FLV player files are attached.
