The output from: udevadm info -a -p $(udevadm info -q path -n
/dev/dvb/adapter0/frontend0) on the original (first) Pinacle device is:

And from the new (second) Pinacle device:

I thought (copied from the wiki) that this might do it:
# Create a symlink for each of two single tuner Pinacle devices
SUBSYSTEM=="dvb", ATTRS{device}=="0x8802", PROGRAM="/bin/sh -c 'K=%k;
K=$${K#dvb}; printf dvb/adapterPC800i/%%s $${K#*.}; exit 0'", SYMLINK+="%c"
SUBSYSTEM=="dvb", ATTRS{device}=="0x8802", PROGRAM="/bin/sh -c 'K=%k;
K=$${K#dvb}; printf dvb/adapterPC800j/%%s $${K#*.}; exit 0'", SYMLINK+="%c"
but then realised the example I copied from was a single card with dual
tuners. Any help greatly appreciated.
