Thanks for sharing but i just wanted to know if it would be usefull for WMPC or not?? any ideas??

No it wont be useful for WMPC, x64 codecs are capable of working with x64 programs like WMP64, Movie Maker, etc where as x86 codecs are capable of working with x86 programs like WMP32 and WMPC. Windows XP x64 just have 32-bit flavour and not WMP64.
