Other frequency, where FTA channels will be available.
Now you have scanned a frequency, where everything is scrambled, so nothing to stream (without decryption).
And puzzling is that to scan 12,284 H you had to input 12,298 H.
If you have to enter a frequency with 14 MHz difference (and this might explain why you cannot receive anything - your satellite setup is somehow very bad), then maybe try 12336000 (which really will be 12322H + 14 MHz) - a lot of FTA there, so good to test.
Hot Bird table:
https://www.flysat.com/en/satellite/position/13-eAdd 14 MHz to anything with FTA channels and try to scan, maybe it work.
After scan - select checkboxes on the right of FTA channel and checkbox on the bottom and go to Media Player Classic.
