[mythtv] 6200ch oddness with 6200 Comcast STB

Sorry for the long and verbose post.  I have to admit,
I know very little about the 6200 and firewire.

If I compile the default 6200ch in cvs I get the
following output when I try to change a channel.

# 6200ch -v 2
rom1394_1 warning: read failed: 0x0000fffff0000414
error reading config rom directory for node 1

Since my stb is on Port 0, Node 2 (as I can see and
hear the cable stream in Mythtv) when I set the node
as 2 - and verified in gscanbus, I get the following
information.  The Vendor ID, Spec ID, and SW version
are all correct.  With gscanbus the model id is the
odd 0x00000000 but 6200ch shows it as 0x0000620a.  I'm
not sure which is correct.

Here is the output with 6200ch being forced to node 2:

# ./6200ch -v 2
node 1: vendor_id = 0x00000ce5 model_id = 0x0000620a

If I do plug the cable into the other firewire port on
the 6200, I don't see any output on Mythtv (even after
changing the node numbers).
