I should have told you that I am looking into / using this tutorial series, sorry.
I got sidetracked looking for the DirectShow 8.1 and the GraphEdit application.
Other than that I feel it is most intelligent tutorial on the COM / DirectShow available and I should be able to integrate it with samples from the DirectShow 8.1. (This is where I “discovered” Gstreamer ).
But I feel most of the folks using anything but VC 6.0 do not know about it!
Many thanks for all your help, appreciate it.
