Doesn't help. dvbtune -i -f 505833 -qam 16 -cr 3_4 gives:

I can get a lower Bit error rate (= 69) if I specify the frequency in Hz 
rather than kHz, but otherwise no change. Running scan_uk-t.sh gives the 
same sort of response for each of the frequencies (conveniently, Crystal 
Palace is my local transmitter). Surely this isn't just a signal 
problem? Wouldn't I see at least something if it was just a question of 
poor reception?

Also doesn't help. No different to using 600 601. I guess the "Could not 
connect to socket" and "No such file or directory" messages from mplayer 
indicate that dvbstream is streaming nothing.

Thanks for the suggestions, but there seems to be something 
fundamentally wrong with my setup. And it seems to be pretty similar to 
Will Tatam's problem. Anyone got any ideas?
