A/V Sync problems are common with three pass encoding.  Use 2 pass encoding instead.  Windows media player shouldn't have a problem with the resulting file (for any reason I know of at least) unless you don't have the proper codecs installed (divx).  Oh, you might try making the second scale value 320 instead of 324 (a multiple of 16)...
