so many people are different m8 i personnally dont use command centre to upload anything i use flashfxp to upload the services.xml and bouquets.xml to var/tuxbox/config/zapit
i find it user friendly and easy to use
but on the other hand lots of people use command centre and they are happy with it and thats fine
ifa will not load your services.xml or bouquets.xml its for flashing images m8 thats all
