Hi, all:

  The simplest way (do not need modification of source code) is deleting "WDM legacy driver".

  Steps: (Only WinNT tested)
    Run regedit.
    go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32
    delete msvideo? which value is Vfwwdm32.dll

  For example:
    if you see, msvideo=o100vc.dll..., msvideo1=o100vc.dll..., msvideo2=o100vc.dll..., msvideo3=o100vc.dll..., msvideo4=vfwwdm32.dll. Then, you can delete "msvideo4".
