Thanks all but still no joy with unzip. Modified code below. FTP'd to /usr/scripts and chmod to 755 and tried 777. I'm stopping on the unzip with "zip flags 1 and 8 are not supported". Re-tried with unrar and it works, with files extracting. I'm suspecting now something is amiss with BusyBox.

Code:
echo 'PLEASE WAIT WHILE BOUQUETS ARE UPDATED'
sleep 3
echo $LINE
wget http://www.darmeth.com/downloads/Darmeth_Motor_45E-30W.zip -O /tmp/darmeth.zip > /dev/null
echo 'DOWNLOAD COMPLETE'
echo $LINE
echo 'UNPACKING BOUQUETS'
sleep 1
unzip -o /tmp/darmeth.zip -d /etc/enigma2 > /dev/null
wget -qO - http://127.0.0.1/web/servicelistreload?mode=0  > /dev/null
sleep 1
echo 'CLEANING /tmp FOLDER'
rm -rf /tmp/darmeth.zip > /dev/null
sleep 1
echo $LINE
echo 'RELOADING SERVICES - PLEASE WAIT'
wget -qO - http://127.0.0.1/web/servicelistreload?mode=1 > /dev/null
wget -qO - http://127.0.0.1/web/servicelistreload?mode=2 > /dev/null
echo $LINE
echo 'DARMETH BOUQUETS UPDATED'
echo $LINE
exit 0
