Problem calling Delphi COM DLL from VB

I've a COM DLL function created in Delphi that can't i can't figure how to "call" from VB correctly.

I've uploaded the COM DLL (plus dependency dlls) and VB demo used to test the DLL to [url removed, login to view] The function in question is COMPOSE.PAS.

Here's the list:

COM DLL - [url removed, login to view] (run [url removed, login to view] to register the dll, ensure that the other 5 dependency dlls are in the same folder).

VB Demo - [url removed, login to view] (click on compose function, that's the problem area - the compose function isn't "called" correct from this VB demo.

Delphi Demo - [url removed, login to view] (this is the equivalent for the VB Demo, but works perfectly with [url removed, login to view]).

The purpose of this COM DLL is to generate a SMIL document, the SMIL doc generated by the VB has corrupted filenames.

This is the TLB for [url removed, login to view]:
