VLC Streaming issue

I have an issue with VLC Media Player Version 2.0.5 while viewing a stream. I cannot view a UDP multicast stream, it simply shows up as a black screen, however I can see network traffic for VLC and I can see data on media information within VLC. If I save the stream I can open it and view it just fine. If I save and display the output it will work too. Anyone know why I cannot view the stream without saving it? This happens on multiple computers running Windows XP and Windows 7. This works properly on the same computers using a different application, so it's something specific to VLC...

Could be a few possibilities.
Please explain>>This works properly on the same computers using a different application, so it's something specific to VLC.

VLC 2.07<< new version
Progressive download?
Can't see it until it's fully downloaded?
Don't know your source or type of streams,
Checking through VLC geeks here is two possibilities.
Please check the drivers on those system are the manufacturer drivers for that video chip and are up to date.
if you get a black screen when watching movie files there are 2 solutions.
 -> Go to Tools->Preferences->Video
 -> Remove the tick for "Accelerated video output (Overlay)"
 -> Try and play the movie again, you should now see output.
 Download proprietary drivers for your graphics card
 Example, NVIDIA  8600 using the default 11.4 open source drivers  shows a black screen when VLC uses "Accelerated video output".
 However, installing the proprietary NVIDIA drivers, VLC will successfully show the movie using "Accelerated video output".

 To clarify the default VLC installation with "Accelerated video output" ticked - works with proprietary NVIDIA drivers - and doesn't without.
The same applies to ATI and others.

I can't specify the source, and I cannot upgrade the software or drivers. However I will try and uncheck that box and see if it makes a difference when the stream is available again. I believe the stream is MPEG-2.
When you have the black screen go to the tools of VLC and Media information and codec information.
Post back what you see ( snapshot?)
Try installing ffdshow
Maybe it can't wont decode mpeg2 on the fly or your bandwidth is not fast enough?

Unfortunately I can't install anything on the system, and I can't provide a screenshot because the system is not on the internet. We do have a deidcated 50MBps link so I know it's not a bandwidth issue, since I can record it fine. I can check again Monday when the stream is going. Until then I'll keep your originol recommendation in mind, and make sure to respond after. Thanks for your assistance.
