[mythtv-users] Unable to find channel in database....

Sun Jul 3 11:30:38 EDT 2005

Hi,

With the seamingly great support for DVB in mythtv, I decided to give it a try 
this week-end. On a Gentoo system I have got it all working (great ebuild!), 
apart from the fact that I cannot get any picture. If I select to view TV, I 
only get 10 seconds of black screen, and then back to the menu.
I also do not have any working xml-tv program list.

I have succeded in searching all free channels (the other I will deal with 
later) from mythtv-setup on my DVB-T card.
I have also selected the appropriate xml-tv script, and downloaded some 
channels. I have then used "mythfilldatabase --manual".

It seams that I have made some mistakes in this area (channel list in 
database?), since mythbackend says;
(Adapter #0 is the one I'm concentrating on righ now, DVB-T) (this after 
programming a manual recording);

If I instead push "watch TV" from the gui, with mythfrontend -v all, I get;

And it contiunes like this for a while, then I get a Segmentation fault

Meanwhile, in the mythbackend (started with -v channel) I get;

Now, the thing is that I don't know anything on how to operate mysql, so I'm 
lost right now... 

Any suggestions on how to continue, or a pointer on how this stuff works are 
greatly welcome!
