[mythtv-users] Firewire 1394 Still Not Working

[Mike Smith]

Hi,

I'm running mythtv 18.2 on a Mandriva 2006 system.

I have been trying for months to get the Firewire
Capture
working.  I have firewire ports on my Asus
motherboard.
Could not get it working and when I heard Jarod could
not get his to work,  I bought a Firewire card that
was reported to work.

Still could not get it to work.  Apparently the
ieee1394 drivers we are using has difficulties when
multiple firewire cards are present.  So, I turned
the firewire built into my motherboard off in bios.
Unfortunately, that also disabled my gigabit ethernet
connections.  I worked with Asus to get a BIOS upgrade
to fix this, so I'm ready to try again.

I have the Scientific Atlanta 3250HD ( SA3250HD ) from
Time Warner Cable in Cincinnati.  I can connect the
firewire port to my TV and watch high def television
from it.  So, the port is there,  AND its turned on.

I connect it to my computer via the PCI firewire card.

I create a connection in mythtv-setup for firewire
using Node=0 and port=0.  I pre-tune the cable box
to a high def broadcast channel ( 912 ) and try
to watch LiveTV in Myth.  I get the following
in the mythbackend.log file:

Sorry for the long post.  I know people have this
working.  I know Time Warner in Cincinnati is 
delivering content via the firewire.  I just can't
get my particular installation working.  

Hopefully, someone can suggest the next step.  I'm
out of ideas.

Thanks,

Mike
