I have a new problem, i'm trying to render subtitles over a video... but i'm
not sure the best way to do this.

I have created the subtitle filter as a renderer. When it receives samples
it querys for the filtergraph, searches for VMR9, if it finds it gets the
alpha bitmap interface, and works that way. It works fine.

Is this the correct way to do it... i had another attempt at actually making
the subtitle filter have an output pin and connecting to the vmr, but not
actually sending it samples... just using the alphabitmap interface. Is this
a better way to do it ?

Is the way i'm doing it now by querying the graph for the vmr9 and using it
that way the correct way ? Or is there another alternative ?

Thanks,

Zen.
