Maybe this will help somebody else?:

Seems topfield 7700 hsci got a little bug for watching the german hdtv channels on the
transponder data, after like updating to application version 7.00.31

To watch anixe hd , prosieben hd and sat 1 hd do the following:

after doing the autosearch, go to the menu Sat/TP Edit (oder Transponder Editor)
then change the transponder on frequency 12721 to
Symbol rate : 22000 KS/s
Mod: Horizontal
Modulation: DVB-S2/8PSK
FEC: 2/3
Pilot: On

save it and enjoy...
