[Live-devel] problems with streaming

I have still not been able to reproduce this.  I was again able to 
successfully stream your example file from one machine - using either 
"testMPEG1or2AudioVideoStreamer" or "vobStreamer" - and receive/play it on 
another machine - using VLC.  I never saw the 'freezing' problem that you 
mentioned.  Sorry.

FYI, I have left online an example of a working MPEG-2 Program Stream file 
that you can try:
         http://www.live.com/test.mpg
(It's a 15 MByte file.  I'll leave this online for the next few days.)

Are you able to successfully stream this file using 
"testMPEG1or2AudioVideoStreamer", and play it using VLC?  If not, then the 
problem must be at your end somewhere.  (I assume you're using a fairly 
recent version of the LIVE.COM code?)

Does the problem occur only if you're streaming over a network?  If so, 
then are you sure you have enough network bandwidth between the sending and 
receiving computers?  Your test file streams at about 7 Mbps, which means 
(in practice) that 10 Mbps Ethernet won't be enough.  Nor will 
802.11b.  You'll need 100 Mbps Ethernet or higher.  Perhaps your LAN has 
trouble handling streams with these bitrates?
