Tvheadend

I've been trying to figure out how to setup live tv on my Raspberry Pi using tvheadend.

I've bought a stick that is supported according to linuxtv.org. It's called a Digital Rise Tiny USB 2 Ter beetle and driver is supported in kernal. since 2.6.13. Hardware Zarlink_MT352 and firmware is VP7045-01.fw.

I have downloaded the code with the following command:

cd /lib/firmware
sudo wget http://www.linuxtv.org/downloads/firmwar...7045-01.fw /etc/init

When I plug it in, under tv tuner it says it's a Twinhan VP7045/46 USB DVB-T.

I scan for muxes and it picks up 5 of them. It scans them but says 0 services and I can't map them. Under the multiplexes tab I can see the frequencies etc and they match up with what they should be according to this site: http://www.ukfree.tv/txdetail.php?a=SX531555

I know I'm getting a good signal as have plugged the Arial lead into the tv and tune all the freeview channels. On the tvheadend it says signal strength 0 and a high bit error rate:
