As i already wrote - SET_PARAMS is _NOT_ enough. Please try yourself. 
Unload/Load the module and simple issue a DVBFE_SET_PARAMS (NOT
GET_INFO) and it doesnt tune/lock at least for STB0899 and it also
complains in the dmesg with:

	stb0899_search: Unsupported delivery system 0
	stb0899_read_status: Unsupported delivery system 0
	stb0899_search: Unsupported delivery system 0
	stb0899_read_status: Unsupported delivery system 0
	stb0899_search: Unsupported delivery system 0
	stb0899_read_status: Unsupported delivery system 0

although i set

	dvbfe_params.delivery=DVBFE_DELSYS_DVBS2;

Its not a bug in szap - its a bug in the API - There is a delivery in
the dvbfe_param and i set it correctly - and it gets ignored. Running
zap before running my program causes it to work because zap runs
an GET_INFO ioctl which _SETS_ a delivery mode.
