What do you mean by running directly from commandline (mircrosoft 
framework)?   Are you meaning executing a SHELL COMMAND from within say C#?

I am using VS2008, .Net Wrapper (MS Framework) and running 50+ 
simultanious streams within an application...  So issue I dont believe 
it is in the framework your choosing..

What would be helpful:

What command are YOU running?  If your running from within a program, 
some sample code be helpful..  Seems your playing a playlist vs. playing 
a file directly?  a sample of that playlist would be good too.  Also 
make note that playlist handling in the .NET VLC wrapper does not work.  
Most folks manually handle switching thru playlists in code.
