/dev/video0 is now /dev/videopvr150

I think I need to amend my "change-channel.sh" in four places,
indicated by <<<* right? Preceding "old line" is commented out"#"
Good?

REMOTE_NAME=DCT700
cmd="$1"

/usr/local/bin/check_stb 1>/dev/null 2>/dev/null || :
sleep 2

case $cmd in
    [0-9]*)
    for digit in $(echo $1 | sed -e 's/./& /g'); do
       # irsend -d /dev/lircd SEND_ONCE $REMOTE_NAME $digit
        irsend -d /var/run/lirc/lircdSerial SEND_ONCE_NAME $digit <<<1
        sleep 0.2
        # If things work OK with sleep 1, try this for faster channel changes:
        # sleep 0.3
    done
       # irsend -d /dev/lircd SEND_ONCE $REMOTE_NAME OK
         irsend -d /var/run/lirc/lircdSerial SEND_ONCE $REMOTE_NAME OK<<<2
sleep 1
        #irsend -d /dev/lircd SEND_ONCE $REMOTE_NAME EXIT
         irsend -d /var/run/lirc/lircdSerial SEND_ONCE $REMOTE_NAME EXIT<<<3
    ;;

    *)
        #irsend SEND_ONCE $REMOTE_NAME $cmd
        irsend -d /var/run/lirc/lircdSerial SEND_ONCE $REMOTE_NAME $cmd<<<4
        ;;
esac

Implementing the previous changes turned on the stb when I ran
"/usr/local/bin/check_stb" so yes I think you've found it!!!!!!!!!
Many Thanks!!!

Please confirm or emend changes to "change-channel.sh"   Daryl
