Tvheadend

Hello, sorry for the poor description, I'm quite new to tvheadend.

I've configured my server for IPTV and multiples services merged on one channel.

Priorities of theses services have been set as this :

10 MUX 1 > FHD
9 MUX 2 > FHD
8 MUX 3 > HD
7 MUX 4 > HD
6 MUX 5 > HD
5 MUX 6 > HD
4 MUX 7 > HD
3 MUX 8 > HD
2 MUX 9 > HD
1 MUX 10 > HD
-1 MUX 11 > SD
-2 MUX 12 > SD
-3 MUX 13 > SD
-4 MUX 14 > SD
-5 MUX 15 > SD

Every mux is a m3u playlist.

This may be an overkill but some of them aren't very reliable.

The 2 first don't work as of now.

I was expecting tvheadend to try the 3rd one after seeing the 1st and 2nd one don't work. (and so on with the 4th, 5th, ...) but it keeps going back and forth between the two firsts only :
