[mythtv-users] Firewire troubles Motorola 6412

[Greg Woods]

I've got a Motorola DT-6412 cable box (basically the same as the
DT-6400, but with a DVR in it). I am trying to record from it over
Firewire, and not having any luck. This is a problem that is outside of
MythTV, as I have the same issues using test-mpeg2 to record.

I know that at least some of the channels are good (i.e. available
unencrypted over Firewire), because every now and then I can actually
get a recording using test-mpeg2. Those play back quite well through
Myth (I cheat to test this; I overwrite one of the empty files from a
recording that didn't work with the output file from test-mpeg2, and
then I can play it through Myth). But most of the time, all I get is an
empty file. I have checked plugreport so I know I have the correct host
and node numbers. The channel changer works, because if I schedule a
recording, I can see it change the channel to the designated recording
channel on the box. But all I get is an empty file for a recording.

Is there anywhere I can go for more detailed instructions on setting
this up? Any information I can provide that would help anyone in
assisting me to diagnose this? I have tried powering everything down and
disconnecting the firewire cable, and that does not help. I have yet to
figure out what it is that I do that makes test-mpeg2 work every once in
a while, but I feel like I have to be close.

I am running FC5, ATrpms for 0.19, and 2.6.16-1.2122_FC5smp on a Pentium
4 hyperthreading CPU.

Thanks for any pointers.
