So here's something.  I unplugged the firewire cable and ran plugreport
again, and got the same node0 info as before.   So it would seem that node0
is the firewire adapter on the MthTV machine, and that maybe I had a bad
cable.  Got a new cable and ran plugreport and got

steve at steve-EP45-UD3P:~$ sudo plugreport
Host Adapter 0
==============

Node 0 GUID 0x00e6bc100000241d
------------------------------
libiec61883 error: error reading oMPR
libiec61883 error: error reading iMPR

Node 1 GUID 0x848dc771a2900000
------------------------------
oMPR n_plugs=1, data_rate=2, bcast_channel=63
oPCR[0] online=1, bcast_connection=0, n_p2p_connections=0
channel=0, data_rate=0, overhead_id=0, payload=0
iMPR n_plugs=1, data_rate=2
iPCR[0] online=1, bcast_connection=0, n_p2p_connections=0
channel=0

Alright then, getting somewhere!  But I tried to run 6200ch and got:

steve at steve-EP45-UD3P:~$ sudo ./6200ch -g 0x848dc771a2900000 -v -q
starting with node: 0
node 1: vendor_id = 0x00848dc7 model_id = 0x00001286
Could not find Motorola DCT-6200 on the 1394 bus.

The model id is the same as what the box diagnostics gave, but the vendor
is different. So I recompiled with the different vendor id and it still
returns the same message.  Sigh.  Not to sure where to go from here.
