[mythtv-users] Timeout Scanning 0 -- no signal

[Miroslav Suchý]

Short story:
I can not tune up any channel on my DVB-T card. Everytime I got error:
Timeout Scanning 0 -- no signal

More details for those who is interested in:
I have DVB-T card named "LifeView FlyDVB-T Hybrid". It works perfectly 
and I'm watching all available channel in Kaffeine. But then I wanted to 
try MythTV...

So I grabed MythTV packages from debian-multimedia.org (I have Debian 
Unstable BTW) which is in version 0.20.2.svn20080126-0.0. I set up 
everything according documentation. Mainly I done:

1) I created "Capture card" Type: DVB DTV Capture Cart (v3.x). Frontend 
has been correctly detected as  Philips TDA10046H DVB-T.
2) I created "Input source". I set "Listinings grabber" to "Transmited 
Guide only (EIT)" and channel frequency to default. In general setup is 
frequency set to europe-east.
3) In "Input connection" I conected this two together I choose "Scan for 
channels". Then I tried all options. Mainly I tried:
	a) change "scan type" to "import channels.conf" and put there full path 
to channels.conf file. Then "Next". It search for while (Signal strengt 
60%, SNR 99%) and it ended with
            Timeout Scanning 0 -- no signal
	b) full transport search.  Then "Next" and I got:
	   Timeout Scanning Multiplex #1 -- no table

In both case I got zero channels listed.

Even if I manualy create channel with values extracted from Kaffeine 
and/or scan, I got blank page in fronted with error "I cannot lock 
channel...".

Can you point me what I'm doing wrong? Or where is the possible error?
