Bypassing the Sequence Grabber

[rob]

Thanks, Steve, 

Sample code would be just great! 

I'll try and put together some minimal "art code" as soon as I
get back and get de-jetlagged (I'm off in Italy for 2 weeks).
I'm realizing how little I know, but it's my understanding that
under every SG call are a bunch of VD calls, and that if I want
to get e.g. a quickcam to work I need to set up a "decompression
chain". I'm hoping things will be faster as well as simpler in
VDxxx land, as I don't need audio. 

Thanks again, 

Rob
