As for the question of .swf or .flv… they are nothing alike, except that they are used by Flash. The swf is a proprietary, compiled file, sort of a self contained program that runs in a Flash player.
The .flv is a container file format (sort of like a box) which contains both an audio file inside it and a video file inside it. That’s all… there’s nothing inside it to play those 2 files.
