Got this from my supplier.

Removing the Enigma 2 script
Whilst watching a channel press the down arrow on the remote
then press the blue favourites button
highlight the bouquet that you want to delete first then press menu button
then remove entry
then yes to remove
then repeat the same process until all the IPTV bouquets are removed.
once they are removed, press the menu button again, but this time you want to purge deleted bouquets.
Then ftp into the box and go into /etc/enigma2 and delete all the iptv.sh files
Then go into /etc/epgimport and remove all the files except:
readme.txt
rytec.sources.xml
satmate.sources.xml
and then finally go into /etc/cron/crontabs and remove the root file.
Then reboot.
