Re: Can't see my tuner card? [In reply to]

Since then I downloaded and installed V4L and it now shows up in lspci.

Of course, NOW I can't find channels … (dvbscan is saying "Failed to open
frontend").

Re: Can't see my tuner card? [In reply to]

I don't think I *have* a mythtv user. At least, I don't see one in my Users
Settings. Do I need to create a custom user named mythtv?

Please bottom post. It's quite hard to follow this conversation otherwise. It
would also help if you trimmed the signature the mailing list places at the
bottom each time.

To answer your question: if you installed mythtv as a distro package then the
mythtv user is likely classified as a 'system' one. This means you won't see it
just doing a list of users. There'll be a way of showing system users, often as
a menu option.

The User Settings program doesn't appear to have a menu option or a secret
way to see the system users, as far as I can tell. I'm already a member of
the video group, too…

From the DVB wiki http://www.linuxtv.org/wiki/index.php/Dvbscan

Scanning for channels you can receive
*Note:* If you get an error 'Unable to query frontend status', try using
'scan' instead.

Also try w_scan too. If nothing works try setting more permissive mode for
the device:

$ sudo chmod -R 664 /dev/dvb

When I use scan, it does scan for channels, but I find 0 services. I didn't
figure I'd have a great list of options given that I'm using OTA, but I
figured I'd get SOME channels, maybe, like four or something.

I know finding 0 channels can mean a lot of different things, so where do I
start?

Start by connecting a proper rooftop HDTV antenna. What antenna are you
using at the moment? Do you have an SD/HDTV at home? If you have and it
scans all SD/HD digital channels then use that antenna.

I don't have access to the rooftop in my living situation. I just have an
indoor antenna hooked up to the tuner card. My TV's HD, but I don't think
it has an antenna builtin… I never thought to check.

When all else fails:

or even:

Other than portables, I've never seen a TV with antenna built in.

The first thing you need to do is *prove* that
you are in fact getting a signal at teh
connection you are putting into your tuner card.
That means taking a TV to that location, putting
the same plug from the same cable into the TV
instead of the tuner card - and checking that you
can get at least one channel.

Then double check that the pin isn't bent on
either the plug or the socket on the card and
reconnect that cable to the card. AT this point,
you now know that there is a signal and if you
don't detect anything with a scan then either the
card or the supporting software is faulty.

Of course, if you can't get anything on the TV, you need to fix that !

The pin IS a little wonky on one end, but with coax, doesn't it by nature
force the pin into the right position?

I scanned for channels on the TV with the antenna and found none, but some
were black and some were snowy. Does that tell us anything useful?

A friend of mine has a different antenna we're going to try next; I am not
optimistic that my landlord will be helpful with the antenna situation, so
if I don't have to involve him that's best.

There is a canadian.website http://digitalhome.ca that has a wealth of OTA antenna information.

Pay a visit to their OTA forum and take a look at their FAQs. I learned a lot from them.
