Well, I'm stumped. How about starting from scratch?

Disable your existing rules by renaming it to digital-cards.disabled.
Paste the following into new file test.rules. Ensure they are all single  
lines, i.e. remove newlines from your mail client.

# Match all dvb devices
SUBSYSTEM=="dvb", SYMLINK+="test1"

# Find Leadtek
SUBSYSTEM=="dvb", ATTRS{device}=="0x8852", SYMLINK+="test2"

# Check C shell. Demonstrate failed program
SUBSYSTEM=="dvb", PROGRAM="/bin/csh -c 'echo test3'", SYMLINK+="%c"

# Check bash.
SUBSYSTEM=="dvb", PROGRAM="/bin/bash -c 'echo test4'", SYMLINK+="%c"

# Original
SUBSYSTEM=="dvb", ATTRS{device}=="0x8852", PROGRAM="/bin/sh -c 'K=%k;  
K=$${K#dvb}; printf dvb/test5/%%s $${K#*.}; exit 0'", SYMLINK+="%c"

# Bash version
SUBSYSTEM=="dvb", ATTRS{device}=="0x8852", PROGRAM="/bin/bash -c 'K=%k;  
K=$${K#dvb}; printf dvb/test6/%%s $${K#*.}; exit 0'", SYMLINK+="%c"


Assuming your Leadtek is still on adapter6 run the usual test:

udevadm test $(udevadm info -q path -n /dev/dvb/adapter6/dvr0)


Report the value of DEVLINKS. I get:

DEVLINKS=/dev/dvb/test5/dvr0 /dev/dvb/test6/dvr0 /dev/test1 /dev/test2  
/dev/test4
