Thanks! Well now szap gives me pids: calculon dvbstream-0.5 # szap -n 1 reading channels from file '/root/.szap/channels.conf' zapping to 1 'BBC 1 London': sat 0, frequency = 11739 MHz V, symbolrate 27500000, vpid = 0x0900, apid = 0x0902 using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' status 01 | signal a533 | snr 7932 | ber 00000000 | unc 00000000 | status 1f | signal b93e | snr c564 | ber 00000057 | unc 00000000 | FE_HAS_LOCK But dvbstream isn't being very helpful: calculon dvbstream-0.5 # ./dvbstream -o -ps 0x0900 0x0902 dvbstream v0.5 - (C) Dave Chapman 2001-2004 Released under the GPL.

I've tried a few permutations of the parameters but no luck. Cheers James
