In addition to playing Flash Video that's embedded in the SWF file, you can also play external video files that reside on the device's memory card or that come from a network address. Unlike with bundled device video, with embedded FLV the device does not need to be responsible for decoding the device video. The Flash Lite player handles the decoding.
Another difference between external device video and external Flash Video is that to play an external device video file, you pass the absolute or relative file location or URL of the video file to the Video.play() method, but when you play an external Flash Video, you use the methods of the NetStream class rather than those of the Video class to control the playback.
