Tvheadend

Hello,

a reason could be that the drivers for your stick are not included in the krenel of your OpenELEC. You can check this when logged in with SSH using:
lsusb - this shows the connected devices, here you should see your stick conected e.g. for my Freecom Stick(here recognized as WideView)stick:
#lsusb
Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001 Device 004: ID 046d:0b07 Logitech, Inc.
Bus 001 Device 008: ID 14aa:0226 WideView Technology Inc.
Bus 001 Device 006: ID 046d:c71e Logitech, Inc.
Bus 001 Device 007: ID 046d:c71f Logitech, Inc. diNovo Mini Wireless Keyboard

dmesg | grep dvb - check if a dvb Driver is loaded, for my system stick is loaded

If your kernel does not include the first try the newest version of OpenELEC - actual 3.0.6 with kernel 3.6.11. If this does not help you have to compile a kernel including the Drivers for your stick

If the stick is present with loaded drivers and still causes problems try a bigger power-supply (e.g. for iPAD)

Thanks for help,

Drivers are recognized, I do get /dev/dvb/adapter0 devices when I plug in. I just tested tvheadend on Laptop running Mint 15, got same results as openelec - no sources/channels. Not sure where to look for logs to find out more. On Mint laptop I'm able to use dvbscan to make channels.conf, and tzap to lock on a channel, also mplayer can display MPEG2 stream. I'm puzzled, why dvbscan finds channels and tvheadend skips them. Weak signal? Crappy dvb-t devices? Wrong multiplex frequencies?
As for power I use powered USB hub to connect my devices.

Anyway thanks for lending a hand. I've dropped this for a while, until I have any ideas what might be wrong.

Can we have a screenshot of the adapter config? Specifically, I was wondering whether you've enabled the adapter, but I'm wondering what your other settings are.

Thanks for reply, I hope you need settings in web interface, so here are the screenshots, hope they will help:

And a text file with some info about tuners (dmesg, lsusb...): https://www.dropbox.com/s/09nhykvlnovum4y/elecbox.txt

I'd say that you have the wrong mux frequencies. I suspect that those are the old analogue ones, so the tuner can see them but not decode anything from them, hence the lack of services.

Delete all the muxes you have, click "add mux(es) manually" and enter the following:

Frequency: 490000
Bandwidth: 8MHz

... everything else: Auto

Click "Add". Then repeat to add the following frequencies:

514000
545800
506000
482000
529800

(Data from http://www.ukfree.tv/txdetail.php?a=TQ339712).

Oh, you've nailed it Thank you very much. I could have sworn I've tried frequencies from that site, must have been doing something wrong. As soon as I’ve entered those muxes - magick - I can watch live TV.

Thanks again.
