In Ubuntu, the mythtv-backend package installs a file that is supposed
to provide it with access to firewire devices:

root at mypvr:/lib/udev# cat rules.d/41-mythtv-permissions.rules
#For firewire capture devices, we need access rights
#to raw1394.  Note, that this may be a security risk
#because devices on firewire can then do anything they
#please as root on your system.
KERNEL=="raw1394", GROUP="mythtv"
