Dear all,

I am having problems with a full featured TT-1200 dvb-t (sometimes also
called technotrend dvb-t premium) card. 

It does not find the frontend and if I manually fiddle with the code (I
simply had to remove the break in line 2176 of av7110.c in hg to allow
fallthrough) to make it load the Spase SP8870 DVB-T it successfully
registers this frontend and loads the sp8870 firmware but then it still
refuses to tune to any channel...

As the card is listed as supported I am a bit confused what is going on
- any ideas?
