I've just recently made the jump to digital cable when I worked out
that I could save $3 a month with a bundled cable/internet promotion
Time Warner was running here in Raleigh. Since I don't have an HDTV,
I'm more or less intellectually satisfied with using an IR Blaster and
capturing from SVideo. I wanted to try getting the firewire interface
working first though, but what I quickly discovered is that there's
not a lot of leeway in between working and not working.
The box seems to be detected fine, which actually is what's confusing
me. If it wasn't being detected AT ALL, I'd just say the ports
weren't working and debate going to raise a fuss.
Upon plugging in, dmesg shows:
ieee1394: Node added: ID:BUS[0-01:1023] GUID[001cea0a3cc20000]
ieee1394: raw1394: /dev/raw1394 device initialized
ieee1394: Node suspended: ID:BUS[0-01:1023] GUID[001cea0a3cc20000]
ieee1394: Node resumed: ID:BUS[0-01:1023] GUID[001cea0a3cc20000]
plugreport shows:

iMPR n_plugs=0, data_rate=2
But test-mpeg2 just gives:
libiec61883 warning: Overlayed connection on channel 0.
You may need to manually set the channel on the receiving node.
Starting to receive
and sits until I kill it.
And firewire_tester just gives a long string of fail:
./firewire_tester -n 1 -p -r 10
Action: Test P2P connection 10 times, node 1, channel 1

Any suggestions while I wait on the ir blaster I ordered to arrive?

<font size="+1"><font face="sans-serif">I'm not familiar with your STB
(mine's a Motorola 6200), but a couple of things to check out/try:<br>
<br>
- go into mythtv-setup, delete your firewire capture card (in 2.
Capture Cards), unplug your STB, wait 10 secs, plug it back in, give it
a minute to start up and then add your firewire again (if you haven't
waited long enough the GUID won't appear). Select "Broadcast" rather
than P2P - at least on my 6200 it's WAY more stable - and set speed to
400. Make sure you give it a connection in 4. Input Connections.<br>
<br>
- Try: <br>
<br>
./firewire_tester -B -P 0 -n 1<br>
<br>
This will attempt to stabilize the broadcast connection.<br>
<br>
- If that still doesn't help, try resetting your bus - I use a program
called gscanbus - just google it and compile it, then type gscanbus in
a terminal. A box will pop up identifying all your firewire
connections. Hit the Force Bus Reset button, then run firewire tester
as above.<br>
<br>
If that still doesn't work, perhaps some sort of DRM is being employed
by your cable co - either CCI or 5C. There should be a way to access an
onscreen menu for you STB and determine which, if any, channels are
copy protected (and therefore unwatchable via the firewire) and also
what form of copy protection is being used, tho I can't tell you how to
do that on your particular box...<br>
<br>
My firewire connection has been pretty solid for months now.<br>
<br>
Cheers!<br>
