I don't think you understood what I've said.
I did some research and apparently you're suppose to use "reverse polarity lnbs" (expensive), for that reason.
Every time the signal bounce of the dish it changes polarization and since I've in torodial dish 2 bounces like those, I get the other polarization and can't use the "normal" satellite.xml file.
I use regular standard lnbs so I guess I'll have to do with my solution for now.
I need to find (or create) a tool like http://satellites-xml.eu/ which will generate those reverse values for me.
Hope one already exist.
That's what some light reading taught me, anyway. I need to research this a bit more.
