Hoi Hika, I did try your suggestions and still no symlinks.

Hi Roger, I commented out the changes Hika suggested, corrected the
device ID, disabled my capture-card.(rules), and still the udevadm
tests show no symlinks:

DEVNAME=/dev/dvb/adapter6/dvr0
DEVPATH=/devices/pci0000:00/0000:00:04.0/0000:02:00.0/dvb/dvb6.dvr0
DVB_ADAPTER_NUM=6
DVB_DEVICE_NUM=0
DVB_DEVICE_TYPE=dvr
MAJOR=212
MINOR=2
SUBSYSTEM=dvb
TAGS=:udev-acl:
UDEV_LOG=6
USEC_INITIALIZED=26583154
run: 'udev-acl --action=add --device=/dev/dvb/adapter6/dvr0'
daryl at daryl-A780L3C:~$

DEVNAME=/dev/dvb/adapter0/dvr0
DEVPATH=/devices/pci0000:00/0000:00:14.4/0000:04:01.2/dvb/dvb0.dvr0
DVB_ADAPTER_NUM=0
DVB_DEVICE_NUM=0
DVB_DEVICE_TYPE=dvr
MAJOR=212
MINOR=6

TAGS=:udev-acl:
UDEV_LOG=6
USEC_INITIALIZED=28980305
run: 'udev-acl --action=add --device=/dev/dvb/adapter0/dvr0'

Both still showing:
