Is anyone on this list familiar with the DirectShow plugins? I have tried to figure out this AMCrossbar problem that I described below, but to no avail. There are a number of VB examples out there, but they are all different enough from the interfaces exposed by the MBS DirectShow classes that I can't seem to duplicate the functionality. My next option is to ask on the Xojo forums, but I figured that I would start here since this is MBS specific.
