i have a dcr that load all short sound internaly, and the long sound are being loaded externaly by external cast.
the movie start playing with all the short sound and later gets to the long sounds. it is possible to order the dcr to download the external sound in the background while playing? so when the playhead reach the point the movie calls the external cast they are ready to play
right now it seems that when the playhead reach the point it needs to play the external sound, it start to stream it online.
