  So, assuming that the XP box starts the isochronous transfer, what is the
proper way to capture on the Linux side? Would it be like any other
isochronous transfer except that the Liunx box would not have to call
raw1394_iso_recv_start(), since the XP box is doing this for you? So, you
would call raw1394_iso_recv_init() then jump right into
raw1394_loop_iterate() without ever calling raw1394_iso_recv_start().
  Also, is there a way for libraw1394 to detect a isochronous transfer
start or stop on a particular channel initiated by another node.
