I was able to connect to a stb last weekend.  It got a little further 
but still no eureka.  I connected to a Pace DC757X and it gave me the 
following.

[root at tanson ~]# /usr/bin/plugreport
Host Adapter 0
==============

Node 0 GUID 0x00308d0120435263
------------------------------
libiec61883 error: error reading oMPR
libiec61883 error: error reading iMPR

Node 1 GUID 0x005094000003f993
------------------------------
oMPR n_plugs=1, data_rate=2, bcast_channel=0
oPCR[0] online=1, bcast_connection=0, n_p2p_connections=0
    channel=0, data_rate=0, overhead_id=0, payload=146
iMPR n_plugs=0, data_rate=2


The guid still doesn't appear on the setup screen.  The computer was not 
connected to the network at the time (used my neighbors stb, but no 
network in the room)...does it need to be?  Also, I was hesitant to play 
with his settings, so I'm not sure if the port is enabled.  So, what's 
my next move...does the above look correct?

By the way, he seemed to have a bad connection on his HDMI cable.  When 
I barely touched it, the TV appeared to reconfigure (goes blank for a 
few seconds, then returns with a picture).  Are these connections 
usually this touchy?
