FLV is a "Flash Live Video" file. It is a format that is designed for web playback, offering high rates of compression. Several products convert video files to FLV format, including the FLV Hosting Encoder, or at www.flvencoder.com Sorenson Squeeze, and
the On2 (Wildform Flix)
There are 2 popular methods to playback your FLV video file - Progressive Streaming and Flash Server side Streaming
The Flash Player browser plugin can play an FLV, but that FLV, must be either embedded in or linked to a SWF. That is, you can't just put the actual FLV on an HTML page. You can however reference the FLV file using action script and SWF (the player controls) which now opens up the door to brand your player, add colors and logos, skins, and links to further information.
Flash Player, the embedded plugin that is in 98% of all internet browsers, and allows playback of Flash SWF files. It is a preferred method because there is no need for a 3rd party download such as Real Player WMP, or Quicktime.
Recent additions have now included playback of an FLV video file. This separates the SWF from the video so allowing faster playback
A Progressive Download in Flash means you are able to watch the video while the rest of the video is loading into the player and is caching into the users temporary internet files
Streaming RTMP - Flash Media Server or Red5 or Wowza Streaming
Flash Streaming Server works differently by using the Flash Player, you can command it to stream directly from the server, with no caching into computer temp folders. This method is preferred for videos longer than around 15 minutes
FLV's being played remotely from the server use Streaming Playback. If the FLV file is not playing through a Flash Server you won't be able to use Streaming Playback.

I want to dig deeper into the meaning of progressive download. If I post a video file and make it available for progressive download, can a user download the file to his hard drive and then watch it later? How would the user figure out how to make the file that's on his hard drive run on the player? What player would he even use for that matter?
In case my questions don't make sense, here is what I am doing now. I post WMV files and make them available for download. Some viewers click the links, save the file to their computer, then later in the day, they simply find it on their computer, double click it, and it begins to play in a windows media player. Can I achieve the same behavior using flv files?
