"Cannot stream between VLCs in VISTA"

We're doing a project on "REAL TIME VIRTUAL CLASSROOM" using VLC plug-in
in Microsoft Visual Studio '08. We tried streaming b/w two pcs, one
running "Windows XP SP3" and another "Windows Vista Home Premium - 32
bit os", it worked. But when tried on two pcs running on "Windows Vista
Enterprise - 32 bit os", only audio was getting streamed, video didn't
get stream, only a BLACK window came. Pcs have "Nvidia Quadro FX570"
video cards installed.

You sure you have matching video codecs on both machines?
