That's usually what I get when I have the wrong QAM and FEC for the 
transponder. It locks on, but just doesn't read anything useful. I've seen 
you're supplying qam and fec on the command line and for all but the ITV 
and C5 transmitter QAM 16 and FEC 3_4 should be right. ITV / C5 have QAM 64 
and FEC 2_3.

are you selecting the right PIDs on command line. For BBC-1 for example 
these should be 600 for video and 601 for audio (I believe these are the 
same around the country).
