As your devices are regenerated each reboot by udev if you change attributes
with common unix command your changes won't be persistant.
You will have to change the udev rules.
The file to modify is usually : /etc/udev/permissions.rules.
look for the line :
KERNEL=="raw1394", GROUP="audio"
and change GROUP="disk" to "video" or "audio"

reload udev :
# /etc/init.d/udev restart
reload raw1394 device :
# rmmod raw1394 && modprobe raw1394

David.
