Yes, does work both standards, and scanning/editing 8PSK transponders. I wrote
this code alone. Patch file is very is very complicated, and without comments
it's worthless. I'll try to go this week to publish. It requires consultations.
I changed many files, not only dvbchannel.cpp.

Whether any of you understand Polish ?
