The current dvb driver of 2.6 kernel for Philips su1278
tuner have not good setting for stv0299 frontend, and have
no lock with high symbolrate transponders.
I changed su1278 settings in budget-ci.c file.
I tested transponders from SR 2900 fec 3/4 to SR 44950 fec
7/8 with TT budget S1102 dvb-s pci card (like nova-ci).
