Bug Description
Binary package hint: kino
On a fresh and completely updated 32bit Gutsy, Kino refuses to capture. Error message: "WARNING: raw1394 kernel module not loaded or failure to read/write /dev/raw1394!"
Loading raw1394 (sudo modprobe raw1394) and changing KERNEL=="raw1394", GROUP="video" into KERNEL=="raw1394", GROUP="plugdev" is required (which is not too good for security reasons).
Average user cannot be asked to perform such complicated steps just to capture a video.

This has always been an issue for IEEE 1394 AV/C DV devices on Ubuntu since Edgy at least. The issue is that the user must have read/write permissions to /dev/raw1394 and the defaults have been changed to accommodate disk devices:
$ ls -l /dev/raw1394
crw-rw---- 1 root disk 171, 0 2007-09-06 05:23 /dev/raw1394
So the user needs to be added to the 'disk' group:
$ sudo usermod -aG disk ${USER}
and then log-out/log-in for the group change to take effect.
/etc/udev/ rules.d/ 40-permissions. rules has the following:
# IEEE1394 (firewire) devices ="video1394* ", GROUP="video"
# Please note that raw1394 gives unrestricted, raw access to every single
# device on the bus and those devices may do anything as root on your system.
# Yes, I know it also happens to be the only way to rewind your video camera,
# but it's not going to be group "video", okay?
KERNEL=="raw1394", GROUP="disk"
KERNEL=="dv1394*", GROUP="video"
KERNEL=
Confirmed with Gutsy Tribe-5 64-bit.
