I need to add several quicktime movie to build a 'edited' version (say movie A + movie B...). I have done the same thing successfully in CSharp.

I initiate 2 QAxObject (Apple QuickTime Control 2.0 / {24BA3CAF-4BE8-4AEC-A7C8-6F47D5684602}). Load an Url/Filename in QAx one.(strange thing that i need to load it twice in URL and FileName)

Create a NewMovie in the second, and try to "InsertSegment" in the second Ax Movie, this is where i get this error message :

"Movie.InsertSegment(Movie_source,0,duration_source ,duration) TypeError: unable to convert argument 0 of QAxObject.InsertSegment from 'QAxObject' to 'IDispatch*'".

Already looked at "QuickTime for .NET and COM Developers".

How could i make the "InsertSegment" method accept the QuicktimeControl.Movie as a 'IDispatch*' ?
Is there any other way to do that ?

See Full Code Below:
