Edit: My copy of the Winter Hill frequency list was pre-DSO. Card works fine. I'll keep the below post in place for posterity though.[/b]

I've just bought a Hauppage Nova-T DVB-T PCI TV card (cx23882, cx22702 frontend), which the LinuxTV wiki states should work fine out of the box, but I'm having some trouble: the card doesn't seem to tune properly, so it can't find any channels.

When I try to scan for channels with dvbscan, I get "tuning failed":
Code:
# dvbscan /usr/share/dvb/dvb-t/uk-WinterHill
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
initial transponder 786167000 0 3 9 1 0 0 0

WARNING: >>> tuning failed!!!

WARNING: >>> tuning failed!!!

Done.


When I try to find out information about the frontend with dvbsnoop, I get an ioctl error:
Code:

So, does anyone have any ideas? I've already tried the LinuxTV guys, and they've no idea, but I'm hoping someone here has had the same problem before, and can help out.

Hey Andrew,
Is your freq list post DSO? i.e. is it up to date now most of the UK is digital?
I have the correct frequencies, but I'm having a big prob with a "demux0 - too many open filters" error.
DVB-T works well with xine and gnome-mplayer but gnome-dvb-daemon is borked, and as a result totem won't let me watch telly.

I think a kernel update fixed the problem, it's working now but I don't know why it didn't before! Still have analog switched on where I am, just had a few problems picking up Crystal Palace and my local transmitter. I think my aerial is a bit too big!

Has anyone solved this issue?

I'm fairly sure it was a kernel issue, I think it all got fixed around about kernel v3 time. Hate to say it but probably best to update Fedora to a version with a more up to date kernel.
