USB DVB-T cant find any channels

[Thee]

Hey

Got a USB DVB-T tuner, which is supported by the Kernel, installed the firmware from a guide I found here on the forums, all good, as you can see:

My problem is that I cant find any channels, with any app, tried MeTV, w_scan and Kaffeine. None can get any channels. Actually, w_scan stops at some point with an error. I even installed official drivers and software in Windows and there it couldn't find anything either.

Now, I'm not using an antenna, I have Cable (DVB-C) hooked to a receiver, which has a RF out, from which you can get about 30+ analog channels with DVB-T settings.

I know this because I tried to scan using my TV, with the following settings, country=Germany, source=DVB-T, Scan for analog channels=Yes. And it finds 30+ analog channels, also, an old CRT TV finds the same channels.

This should work, so why can't this tuner find any channels?

It is probably something completely different, but I have to change the transmitter data contained within the default scan files, eg for kaffeine the file is ~/.kde/share/apps/kaffeine/scanfile.dvb

Might be worth checking it is scanning with robust data.

Well I don't really know what I should change there...

[howefield]

Which transmitter are you served by ?

If you mean the receiver, it's this one:

Ok, I figured it out. I cant use a DVB-T card to get analog TV channels. These zillion standards are gonna ruin us someday

So, I think I should get a DVB-C card to be able to receive digital channels, or a analog TV card to be able to receive analog TV channels. Or something that has both...

In any case, someone knows something like that thats not very expansive and works on Linux?

Have you checked you have installed v4l programs as well as enabled v4l in the kernel?
