I noticed that some of the files in the etc/enigma2 folder were updated when I used DreamboxEdit to sort out my bouquets the other day, and my sorting was then shown correctly on my TV screen. So maybe BH used some files and not others.
In any case, I just made a backup of my /etc/tuxbox satellites.xls and uploaded my new one to there, restarted the box aaaannnndddd....
(fanfare and applause )
IT WORKED !! I now see 39E etc. in my list !
Thankyou all so much
(Abu: I will try the backup addon that you mentioned tomorrow, it's getting late..)
