Yes - but it's a *feature*, not a bug.  It's how the RTP demuxer helps 
bring audio and video into sync (complementing the a/v sync mechanism used 
by the general MPlayer code).

Your 'setup' looks correct, but please make sure that you're using a recent 
version (2003.09.11 or later) of the "LIVE.COM Streaming Media" code, 
especially for building "vobStreamer".  (Earlier versions of the code 
contained a bug that could cause problems streaming MPEG-2 video.)

Also, make sure that your LAN is fast enough for MPEG-2 streaming.  A 10 
Mbps Ethernet may not always be fast enough; I recommend 100 Mbps.
