For the benefit of others with a similar problem, who might stumble
across this post, this is how I fixed it. I'm sure there are much better
ways, but this worked for me.
The culprit was the bttv module. From kernel 2.6.16, this module has a
new source file, "bttv-input.c" (it's in directory
"drivers/media/video/", of the kernel source), which defines the
infrared codes for various cards. To stop the codes being recognised,
all I had to do was to pretend that my DVB card doesn't have an IR
sensor. To do this I edited another source file, "bttv-cards.c", by
changing ".has_remote = 1" to ".has_remote = 0". This assignment appears
for each card with a remote and you need to find the one for your card.
Mine was BTTV_BOARD_AVDVBT_771.
I then just executed the following commands as root:
cd /usr/src/linux
make modules
make modules_install
It should all work properly (i.e. all remote signals intercepted only by
lircd) after the next re-boot (or just re-loading the bttv module should
do it).
I'm sure there's a better way that doesn't involve editing source code
(e.g. with an appropriate configuration option), but as I only update my
kernel a couple of times a year, and the above only takes a couple of
minutes, I'll live with this for now.

Thanks Craig, this sounds promising. Can you explain what you mean by
"just used the correct dev/input driver for my card"? I tried setting
the LIRCD_OPTS variable to "-d /dev/lirc/0" (in file
/etc/conf.d/lircd) but this still didn't work.
btw, I now believe that the module responsible for detecting the
additional signals is bttv (thanks to Peter Fern for pointing me in
the right direction).

Now it seams that there are 2 separate modules that are responding
to key presses on the remote, lircd and one other. If I stop lircd,
the system still responds to the remote
I have seen this with my Dvico Dual Digital Card / remote as well.
Using 2.6.16, the four purple buttons work, but nothing else on it does.
I thought lirc was partialy working, but it turns out even if lirc is
not
running the four buttons still work.
I eventually got lirc fully working. Did not change anything else, just
used the correct "dev/input" drivers for my card.
