oh...well the machine where the darwin streaming is running is linux. fedora 8 distribution... but i think every packet should have an id, or am i wrong?

So the machine sending the packets is using Darwin Streaming Server?
What OS is that machine running?

Whether you *can* get the OS's networking stack to set the IP ID to a
value other than 0 (and presumably thus not to set the "don't fragment"
flag), and, if so, how you would do it, depends on the operating system.
  OS X doesn't appear to have a way to request that the flag be turned
*on*, so I assume you're not doing this on OS X.  A quick look at the
Linux 2.6.24.2 IPv4 stack doesn't show any immediately obvious way to
request that the flag be turned on, either.
