Re: [pygame] [BUG] pygame 1.8.1 beta 2 movie module plays MPEG file's sound, but not video

[Lenard Lindstrom <len-l@xxxxxxxxx>]

Well that turned out to be pretty easy. Thanks again Jason.

import _winreg

def get_directx_version():
   key = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, 
r'SOFTWARE\Microsoft\DirectX')
   try:
       version, value_type = _winreg.QueryValueEx(key, 'Version')
       if value_type != _winreg.REG_SZ:
           raise ValueError("DirectX version information corrupted")
       return [int(n) for n in version.split('.')]
   finally:
       _winreg.CloseKey(key)
