<div> The program starts, the video plays (directx window) and the

What do you mean by running directly from commandline (mircrosoft
framework)? Are you meaning executing a SHELL COMMAND from within say
C#?</div></blockquote><div><br></div><div>To test, here what I have done :</div><div><br></div><div>Start, Execute, "cmd"</div><div><br></div><div>cd /d "C:\program file\videolan\vlc"</div><div>vlc -I dummy -vvv --extraintf=logger --logfile=D:\VlcLog.txt "D:\a.avi"</div>
