Cannot find channles in MeTV

Asked by steveb001 on 2010-05-05

Hi
I am trying to configure MeTV to work with my Phiips DV-B Card (The card shows as a tda10046h in MeTV).

When I launch MeTV I see the scan wizard. From there I select the initial scan option and choose my location (uk-Nottingham) and the program scans for channels. However, after the scan there are no channels available.

I have used the inbuilt meter and have seen that that signal strength is 0% whilst the S/N Ratio is 100% - so this is obviously my problem....

I have run lspci and the output is as follows - I can't see any problems here:

However, I have plugged a TV into the socket (using the same TV lead) and it works OK, meaning that there is a signal getting down the lead. Therefore the issue must be with the card, my build (Karmic) or MeTV. The Card works OK (albeit under Windows) and as far as I know I'm fully patched with my build. Therefore I am assuming that there is a problem with MeTV, which is stopping me from scanning for channels.

Can anyone provide me with any troubleshooting tips to resolve this issue?

Many thanks in advance.

First, what Me TV version are you using, the default one from karmic? You need to confirm that your device is working under linux. See if the `scan` command produces any results.

Cheers,

Hi
Thanks for the reply.
I'm using the version supplied by Ubuntu (1.0.0). I have also loaded up Lucid and installed Me TV from the repos (this installs version 1.1.2). Both installations behave the same (i.e. no channels).

When I run scan it prompts me to provide switches. What switches do I need to include so I get the information you need?

Thanks very much

I don't need the information, you do ;)
FAQ #395: “How do I run the scan command line application?”.

Thanks for the link. However, as stated previously, when I run the scan command I am prompted for a switch (as shown in the FAQ you pointed me to). I still need to understand what the scan command will provide me and how it can help (not just pointed to a FAQ which repeats the output I have already been presented with). I take it that as I only receive a prompt for switches that my card is not functioning correctly? Or do I need to provide a switch to nudge the command in the right direction?

An update:
I have installed TVTime and scanned for channels. I have detected several channels (albeit analogue) so I'm assuming that the TV card is OK. Therefore the issue lies with MeTV (as far as I can tell)

Any help would be greatly appreciated as this PC will ultimately be used as a TV (for the kids) so I need to get it working. The alternative is to install Windows 7, which I don't particularly want to do but may not a have a choice.

Hello.....

The following is what i did to create a channels.conf for use with dvb on xine.

scan /usr/share/dvb/dvb-t/au-Newcastle > ~/.channels.conf (the prefixed . makes the file hide ctrl+h in nautilus to view all)

If you where to do something similar you could confirm reception/hardware capability.

Note the dvb-t is for terrestrial, there are other options in the folder, and the location just select the one for you.

Also maybe checkout mythtv, mythbuntu, and my old favorite xine.

Can you help with this problem?
