The dll is not corrupt. It is the 16-bit dll, possibly present for legacy 16-bit support. You must use the 32-bit dll, it seems it called avifil32.dll. Also I guess to get the AVIFILE.H header file, you need to install some MS SDK or the platform sdk. Thomas -- http://mail.python.org/mailman/listinfo/python-list
