Thanks for everybodys help.

Just a summary of what I did for anyone else who may be trying to get the PCI 
version of the Nova-T card working with Mandrake 9.1.

[ Note that as far as I understand, this will work with cards purchased since 
May - as these cards are now the same as the budget Lorenzen cards.

I grabbed the latest dvb drivers from linuxtv.org:

http://linuxtv.org/cgi-bin/cvsweb.cgi/

cvs -d :pserver:anonymous@linuxtv.org:/cvs/linuxtv login
cvs -d :pserver:anonymous@linuxtv.org:/cvs/linuxtv co DVB
cd DVB
make

cd DVB/drivers/

then comment out all but 'CARDS = av7110' in the 'Configs' section of 
DVB/drivers/Makefile and modify DVB/drivers/frontend/Makefile so that 
tda1004x is initialised with debug enabled

62c62
<       $(foreach frontend, $(obj-m), insmod $(frontend) tda1004x_debug=1; )
---
>       $(foreach frontend, $(obj-m), insmod $(frontend);)

[ Note, at the time of writing, debug must be enabled for the tda1004x 
frontent for the card to work properly - anyone have any ideas why this is?]

then

make insmod

[ Note, I have devfs running and this seems to work as is. None-the-less, 
copied the supplied devfs.conf to /etc/devfsd/ and removed the mandrake 
references to dvb in the /etc/devfs.conf file ]

You can compile and use DVB/apps/scan as per the instructions.

I added the following to my initial.h to support the Redruth transmitter in 
the UK.

	/**
	 *  Redruth, Cornwall, (BBC1, ...)
	 */
	{
		.type = FE_OFDM,
		.param = {
			.frequency = 618000000,
			.inversion = INVERSION_OFF,
			{ ofdm:
				{
					.bandwidth = BANDWIDTH_8_MHZ,
					.code_rate_HP = FEC_3_4,
					.code_rate_LP = FEC_NONE,
					.constellation = QAM_16,
					.transmission_mode = TRANSMISSION_MODE_2K,
					.guard_interval = GUARD_INTERVAL_1_32,
					.hierarchy_information = HIERARCHY_NONE
				}
			}
		}
	},

Details for transmitters in your area can be found here (note you should use 
INVERSION_OFF not INVERSION_AUTO):

Running the scan application should help you to create a channels.conf file 
which should be copied to ~/.tzap/channels.conf

You can then compile and run the tzap application in DVB/apps/szap:

./tzap -r "BBC ONE"

leave this running and if your are getting a signal:

in another console type:

cat /dev/dvb/adapter0/dvr0 > output

leave it running for a few seconds then press ctrl-c.

If you've got some data, then the drivers should be set-up ok.

To get a picture, I grabbed the latest cvs version of the dvbtools:

http://sourceforge.net/projects/dvbtools

and run dvbstream, for example:

./dvbstream -f 618000 -ps -o 600 601 | mplayer -nocache -

gets BBC ONE on the Redruth Transmitter - obviously your frequency and pids 
will be different from mine.

Now I'm off to play with MythTV and VDR. :-)
