Thanks very much for the quick response, Frank.  Hmm ...
I wonder if the WinTV-PVR uses the same PCI bridge as
its older cousin, WinTV, which has had Linux support
for quite some time ...

By the way, I noticed that the Visiontech Reference Board shown
at http://www.visiontech-dml.com/kfir_rdk.html is different from
the one at http://www.linuxtv.org/mpeg2/ (presumably manufactured by
BMK-Elektronik).  Will the Linux Kfir driver work on both boards
without change?

OK.  Thanks.  The only hint I can see is KFIR_I_PICT in KfirCMD.h
and KFIR_MPEG_I_BIT_RATE in KfirDef.h, but they don't seem to be
used anywhere in the driver source.  I guess I will have to get
some documentation from Visiontech ...
