I'm not trying to be difficult here.  But I don't understand half the requests
that are made of me.  I really did generate the AVI file from my capture card.  
What else should I say?  It uses an app called MediaExpress.  Is that what you wanted?
This generates AVI files which have no inter-frame compression (no mpeg-like codecs)
and no intra-frame compression (it's YUV422).
