[Red5] Prebuffering video with Red5

[Soren Petersen]

I don't know. I never got the chance to play around with FMS (its too 
expensive for my current budget :( ). I'll check if there is a 
development license or something like that...

The functionality I'm searching for seems to be supported at a number 
places that use video streaming. It is, however, entirely possible that 
all those places are using progressive download rather than streaming...

Anyhow, it seems to be a problem if the user has to wait several seconds 
for the player to re-buffer each time playback is resumed...
