Hello,

I wrote a pseudo driver (fwiso) for IEEE 1394 isochronous
acquisition.  You can get DV data using this driver.  You
can find the driver kit (a patch and some additional files
for the latest NetBSD current) at
<http://www02.u-page.so-net.ne.jp/xb3/mistral/>.  This
driver is for IEEE 1394 OHCI chip (fwohci).  This driver
will work with i386 and parhaps macppc.

You can use fwiso driver as `cat /dev/fwiso0 > file'.  The
obtained file is shown by playdv (a sample program of
libdv).  Libdv is in sourceforge.

Enjoy!
