i have same box and firewire card. but i use both hdpvr and firewire to
record depending on the channel (i am with specturm- time warner in
cal/usa). you did not say above whether you made a channel change
script for the hdpvr. maybe that's whats missing.
mine looks like this:
#!/bin/bash
b=999if [ -f /home/mythtv/fire ]  then    rm /home/mythtv/firefiif [ -f
/home/mythtv/pvr ]  then    rm /home/mythtv/pvrfi
touch /home/mythtv/pvr
if [ "$1" -gt "$b" ]then   6200ch -g 0x6455b1fffe293e3b -4
"$1"else   6200ch -g 0x6455b1fffe293e3b "$1"fi
you would not need the top part, i am just placing an empty file to
know which was last tuned as i have a 'priming' script that sets the
box up for firewire recording.and of course every guid is unique to
box.
script name goes into setup under input connections and it must have
correct privleges for backend to run it.
