the problem is that you can't control how the dct62xx comes up, some will 
allow for broadcast connection, some will only work with p2p.  I have it 
setup as a firewire capture card, Cable Box Model DCT-6200, Connection Type 
Point to Point, Port 0, Node 2.

I can't enable bcast(it never =1), here's my plugreport:
