hi
Still have one or two probs

I have tried both anttis and jan trees, both of them compile but do
not load modules or create dvb device when modprobed

Using the realtek driver (1.4.2) I have the following issue

one (and now only one) mux fails to pick up any channels, the channels
are as clear as day my digibox with the same same connection

>>> tune to: 530167000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_AUTO:QAM_64:TRANSMISSION_MODE_2K:GUARD_INTERVAL_1_32:HIERARCHY_NONE
WARNING: >>> tuning failed!!!

The only difference I can see is this in dvbtune

mux that works

dvbtune -f 482167000
Using DVB card "Realtek RTL2832 DVB-T  RTL2836 DTMB"
tuning DVB-T (in United Kingdom) to 482167000 Hz
polling....
Getting frontend event
FE_STATUS:

The only difference I can see is the SNR and ber (19616)

any ideas
