Marian,

Correct, the KNC1 DVB-S2 has a STB0899 frontend.

I've taken patch 5 and changed the values from 15msec to 100msec and yes 
this really does help! With the KNC1 I was able to tune to the other 
DiSEqC positions just fine.

With the TT-3200 I'm still getting mixed results, even with 200msec. On 
some frequencies I'm not tuning to the correct transponder.

Ex: Hotbird 13.0E 11054.00 H will land me on 11411.00 H. If I tune to 
11411.00 H I end up on 10892.00 H
