What is the difference between the wmp and directshow(graphedt.exe) to play
a asf?

I found the wmp will random drop some same when play asf file which included
my compressed sample. This will lead to the crash of my decoder dmo. But in
directshow ,my dmo work great !
Why ?

WMP uses a DirectShow filtergraph for playback but with a few twists. It
uses it's own graph manager which seems to cause it to issue seek commands a
little differently. Additionally it uses additional filters prior to the
render to control visual, audio effects. Also it is going to use the VMR
by default (if available), you can control this setting by going to
Tools->Options->Performance->Advanced.
