That bit of information is golden :)...

I added the following line to the dev-kernel/build-2.4/insmod.sh script 
where appropriate...

insmod ./tda10045h.o 
tda10045h_firmware=/usr/lib/DVB/driver/frontends/tda10045h.mc

Performing a ./insmod.sh load now generates the following messages... 
(via dmesg)

Linux video capture interface: v1.00
saa7146: register extension 'dvb'.
saa7146: register extension 'budget dvb'.

All looking good... found the right Tuner...


Now.. forgive me if I'm being a newbie... but as I understand it, the 
next bit to worry about is dvbtune... I'm on the Crystal Palace 
transmitter, so I got my frequencies from 
http://www.itc.org.uk/uk_television_sector/reception_advice/digital_trans_guide/show_transmitter.asp?siteID=66 
and used the frequency=1000000*((UHF_Channel*8)+306) to get my frequency 
in megahertz...

build2.4/# dvbtune -f 506000000 -i
tuning DVB-T to 506000000
.....wait here forever.....


So... I did an strace.. just to see what's going on...

We seem to be getting stuck here....

write(2, "tuning DVB-T to 506000000\n", 26tuning DVB-T to 506000000
) = 26
ioctl(4, 0x40046f47, 0xbffffae4)        = 0
poll([{fd=4, events=POLLIN}], 1, 10000) = 0
ioctl(4, 0x40046f47, 0xbffffae4)        = 0
poll([{fd=4, events=POLLIN}], 1, 10000) = 0
ioctl(4, 0x40046f47, 0xbffffae4)        = 0
poll([{fd=4, events=POLLIN}], 1, 10000) = 0
ioctl(4, 0x40046f47, 0xbffffae4)        = 0

Help!...

Thanks ,

Jim
