The class cStreamdevStreamer and it's child classes manage the transfer of the 
data. Mainly the data is read, converted (maybe) and finally sent to a 
cTBSocket object. That happens in the Action() method of cStreamdevStreamer 
(can be found in server/streamer.[ch]). The cTBSocket object is given to the 
streamer on creation. So the easiest procedure would be to derive a new class 
from cTBSocket (or cTBSource, which is the base class of all IO-Classes) 
which implements the TimedWrite method and does it's multicast transfer 
there.

Additionally, you would have to modify the command methods in server/
connectionVTP.c (CmdPORT et al) to create your derivation of the cTBSource 
class instead of the default, TCP-based cTBSocket and give that to the newly 
created streamer class.

Sorry for asking, but why the hell are you a) responding to a totally 
unrelated post instead of creating a new one and b) quoting the whole 
original post below your message without ANY reference to it?
