Hi,

I'm a newbie to dvb (using Mandrake 9.1) and have purchased a shiny new 
Hauppauge Nova-T card for use in the UK on the strength that others seem to 
have got this card running:

http://www.linuxstb.org/dvb-t/index.shtml

Unfortunately, I just can't seem to get it working!

I've search the net and mailing lists. Tried to follow instuctions on HOWTO's 
etc. But I just can't get the card to output any data.

I've downloaded and compiled the 1.0.0 drivers:

http://linuxtv.org/download/dvb/linuxtv-dvb-1.0.0.tar.gz 

and copied ttlcdacc.dll (extracted from a windows install) into 
/etc/dvb/tda1004x.mc

make insmod gives (no errors):

devfs also seems to create the device nodes:

I am based in Falmouth, Cornwall and use the Redruth transmitter:

So I have installed libxml2 and compiled the latest dvbtune from cvs, I seems 
to find a signal, but complains about 'nothing to read':

./dvbtune -f 618000 -qam 16 -cr 3_4  -m

                                }
                        }
                }
        },

gives:

I finally figure out how to I create a channels.conf manually:

BBC-1:618000000:INVERSION_OFF:BANDWIDTH_8_MHZ:FEC_2_3:FEC_NONE:QAM_64:TRANSMISSION_MODE_2K:GUARD_INTERVAL_1_32:HIERARCHY_NONE:600:601

and I think I got tzap to work?

./tzap -r BBC-1

using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 618000000 Hz

But if I try to cat /dev/dvb/adapter0/dvr0 I get an empty file - no matter how 
long I leave it.

dvbstream is no better:

./dvbstream -f 618000 -qam 16 -cr 3_4 -ps -o 600 601

followed by absolutely no data! :-(

I have tried other combinations of qam and cr but to no avail.

What am I doing wrong? :-?

Any help would be *very* much appreciated.

Thank you.
