When I invoke VDGetCompressionTypes(), it returns me a -32766.

SeqGrabComponent seqGrabComp;

VDCompressionListHandle h;

seqGrabComp = OpenDefaultComponent(SeqGrabComponentType,0);

SGInitialize(seqGrabComp);

SGSetDataRef(seqGrabComp,0,0,seqGrabDontMakeMovie);

VDGetCompressionTypes(seqGrabComp,h);

VDGetCompressionTypes() takes a video digitizer component, not sequence grabber component. So after you have properly configured your sequence grabber video channel, you call SGGetVideoDigitizerComponent() to get the the underlying digitizer.
