thank you very much for this input, luca

i took a look at feng. feng is for streaming, right? i'm not talking

for the user it has to be like just DOWNLOADING an ordinary mpeg4/h264  
file that he can open or even progressive download into quicktime.

the files have exactly the same format.

would be so cool if you could help me on that.
