I'm still in hope that the "diseqc 1.2 positioner" dialog have a final fix.
To remember, this are the issues I detected to fix, to make it more friendlly way:

1- Update the "Position" number selector to the number/position it was given in the "More than one position" of lnbs port configurations, when choosing a satellite;

2- Show only the satelites selected in the diseqc tree (of "TV Sources"), in the satellites drop-down list;

3 - Remove the bugged "Positions" button from this dialog.

And then, a help update about configuring antennas, to the novice user will be great...

Again. I am plan total remake this dialog in future. But not busy by other parts of ProgDVB and collect good ideas for positioner dialog. May be you have screen of good realization?

Everything basic is working in that dialog. Cant imagine something really new here.
The dialog still have bugs, and is un-friendly, as I described above. Using it you soon see that.

There´s a general issue with the repeated diseqc messages: it doesnt work in some cards. I tested with a TBS 6925 and a Twinhan 1020A and both them dont send repeated mesages (E1...). But my Prof7301 does send repeats .
