Figured out the first part. I needed to install an "MPEG2 decoder." But I already have PowerDVD 6 w/ valid DX and WMP10 decoder, for some reason reinstalling PDVD allowed my MPEG2 playback. Another weird thing is that WMP10 and PDVD both played MPEG2 files and DVD but my DS app was throwing exceptions (even though they have the same base classes) ?!#!@# Gotta love Microsoft stuff ;-). However I still need help on the second part, the DVD navigation filter. Any help would be great. Thanks

There is a base DirectX dll and there all all the different interfaces i.e. 3D, Sound, Input etc. Eitherway adding all these additional dependency should affect the functionality of the merged DLL, not the merging process itself. I am concerned about the merging. I will add the additional assemblies when required.

You must be joking. You write software, but you want to steal from other people who do the same ? Christian Graus - Microsoft MVP - C++

It works, that is awesome. Thanks for all your help.
