I have 2 Fire DTV S2 linked to a HTPC and I´ve just for the first time installed the latest MediaPortal software. All function very well exept that I can´t find the HD channels after scanning. I know that CD have changed FEC from 2/3 to 3/4 so I´ve made that change in the tuning parameters in the Thor 2/3 file before scanning. What more can I do to catch the HD channels
