[MEncoder-users] Downloading a stream

[jd1008]

Could someone please explain how I might save a video stream?

It is not an ordinary stream like youtube.

When I play it, and I click on the doun-arrow next to
the icon of the firefox add-on "Video DownloadHelper",
it displays many files whose names are all numbers, with
the extension .f4f

I downloaded one of those and it is not playable by any
player I have (mplayer, vlc).

So, how can I save the stream as an mp4 or any of the
formats that mplayer or vlc can play?

Thanx!!
