Seeing Foxt2 Still On BBC red button in morning.

A factory reset does not necessitate re-installation of the CF components. The tuning will need repeating, but this only takes 5 minutes even if you have to do it manually (and you could export the old tuning database and then re-import it, but that might just re-import the problems). The recording schedule can be backed up by WebIF before factory reset, and then restored afterwards.

Menu >> Settings >> Installation >> Factory Default
That did the trick. I also gad to delete the BBC Red Button entry in scedule and then it was replaced by OTA Defeat on the next reboot.
Thanks for the help.
