Firewire support - dvgrab?

[Blake Thornton <thornton@xxxxxxxxxxxxx>]

I'm not sure this belongs on the video4linux list, but I hope someone can 
help me.

I'm trying to get a firewire card going on my redhat 7.2 box (connecting 
to digital video camera).  I am running kernel 2.4.9-13 (as obtained from 
redhat).

I've looked at the following sites:
linux1394:  http://linux1394.sourceforge.net/
raw1394:    http://sourceforge.net/projects/libraw1394/
dvgrab:     http://www.schirmacher.de/arne/dvgrab/

I've installed the following rpms:
dvgrab-1.01-1mdk.i586.rpm
libraw1394-0.9.0-1.i386.rpm
libraw1394-devel-0.9.0-1.i386.rpm
libraw1394-devel-static-0.9.0-1.i386.rpm

I've rebooted.  I'm not too sure how to test my firewire card, but I've 
tried running the program dvgrab.  Here's what happens first:

-----------------------------------------
[blake@sierra blake]$ dvgrab --frames 25 party
raw1394 - couldn't get handle: No such file or directory
This error usually means that the ieee1394 driver is not loaded or that 
/dev/raw1394 does not exist.
-----------------------------------------------

So, I make the entries in /dev/:
[root@sierra dev]# mknod /dev/video1394 c 172 0
[root@sierra dev]# chmod a+rw /dev/video1394 
[root@sierra dev]# mknod /dev/raw1394 c 171 0 
[root@sierra dev]# chmod a+rw /dev/raw1394 

I also inserted the modules:

[root@sierra blake]# modprobe ieee1394
[root@sierra blake]# modprobe raw1394 
[root@sierra blake]# modprobe ohci1394 attempt_root=1 
[root@sierra blake]# modprobe video1394
[root@sierra blake]# lsmod
Module                  Size  Used by
video1394              15536   0  (unused)
ohci1394               17072   1  [video1394]
raw1394                 6816   0  (unused)
ieee1394               24496   0  [video1394 ohci1394 raw1394]

(the unused looks odd to me, but I really don't know)

So, now when I run dvgrab, it does not give me an error, but it doesn't do 
anything either.  I'm not sure if this is a dvgrab error or a 1394 error.  

So, I run testlibraw and get some errors and I'm not sure what they mean.

[root@sierra blake]# /usr/bin/testlibraw
