Well, there's something weird going on with the signal I'm receiving,  
so it might be related to that. I'd expect to find a BBC transponder  
at frequency 505833330, but it's actually at frequency 506000. I have  
to configure VDR to not add new transponders, as when I use the  
channel.conf file eg from the w_scan output below, it tries to retune  
to 5058333, and I loose the picture.

I guess it might be related to that I'm living in a block where I get  
the signal from the socket in the wall, and there might be some kind  
of reamplification of the tv signal. I'm just not knowledgeable about  
dvb-t standards to understand what's going on.

Before I moved into this block, I used to have (using a roof arial)  
in my VDR channels.conf eg.

BBC ONE;BBC:505833330:C34D34M16B8T2G32Y0:T:27500:600:601=eng,602=eng: 
0:0:4164:9018:4100:0

Now I have to use

BBC ONE:506000:I999B8C999D999M999T999G999Y999:T: 
27500:600:601,602:0:0:4164:0:0:0

Maybe someone can explain the difference between the numbers 506000  
and 505833330? The former seems to be just a rounding of the latter,  
but there's a digit too little..


Output from a scan with w_scan, using a nova-t 90002; (I don't get  
any signal / lock when using the nova-t 500.)
