	Interesting... I'm sure you've already tried this as one of the 
undocumented registers in the bt878, right?

	Also, the pcHDTV-3000 card uses that chip as the SDTV capture and 
PCI-bus interface.  It costs quite a bit to play with for gnuradio stuff, 
but it might have other value as well.  The Oren chip that does the 
VSB/QAM demodulation is basically doing software-demod (since it's 
firmware adjustable).  I don't know if the raw data can be had from that, 
but it might be more conducive to uncorrupted streams.
