Why is WS_CLIPCHILDREN necessary to display a DirectShow window on XP (but not on Vista or Windows 7)?

I wrote a program for playing MPEG video in a window (of course, DirectShow will open its own window as a sub window of this window). In Windows Vista and 7, the program works fine. But in XP, the video is displayed only when I set the style WS_CLIPCHILDRENin an external window (i.e. Not in DirectShow). Is this a bug in XP or a model change in Vista?
