Yes it does seem strange remlap. I can never lock any of the DVB-S2 TPs, or the encrypted DVB-S TPs 11449H or 12476V.
All the others I have at some time found OK, although I'm not sure about 10795V or 11564H, not in my list of catches presumably because there wasn't any new channels to report after the bird fired up, having AFAIK simply transferred all the channels from the Nilesats. Will try those tonight if only to complete the list (minus the DVB-S2 TP's unfortunately)
Oh, and the one DVB-S TP always absent for me is 11679H because of the 11679V TP on 5W which seems to be causing cross-polarisation with my LNB, no matter how fine I tune the dish / skew the LNB.
