Python supports being extended using "extension modules"; on Windows they  
are dynamic libraries (DLL). Before 2.5, the extensions ".dll" and ".pyd"  
were both valid; starting with 2.5, only files ending in ".pyd" are  
recognized.
Note that this applies to extension modules *only*, not generic DLLs.
All binary packages targeted to 2.5 use the right name for their extension  
modules, at least all that I know of. You don't have to rename anything.

A .pyo file is a totally different thing; it's a compiled Python source  
(like a .pyc) but with optimization turned on.
