We have created a DMO wrapper around a codec that works on windows
2003 server under WMP 10. I can play custom encoded avi and asf
files. However, the same code base doesn't appear to be loaded by
mobile player on smartphone emulator (wm6 sdk). I've compared the
registry settings between the emulator and the laptop in both the
"CLSID" key and the DirectShow->MediaObjects and they look the same.

Is anyone aware of reason(s) why a DMO wouldn't be loaded under mobile
WMP10 on smartphone?

I'm linking the DMO and the core library static (though I've tried non-
static with same results) and deploying to the \windows folder.

When I try to play an avi file with the custom codec, I get "Cannot
play back the video stream; no suitable decompressor could be found."
If I open an asf file, I get "Cannot play any items in the playlist.
For additional information, on the Now Playing Screen, select an item
and the press menu > error details" which just gives me the same error
as the avi.

My conclusion is that the DMO is not registered correctly but what do
I need to do in addition to COM registry and DMO properties in
DllRegisterServer()?

Any help or ideas on this will be greatly appreciated!

Thanks,

Mike
