	Dave Chapman (the author of dvbstream) kindly directed me to the CVS 
repository of dvbstream and that compiles nicely against the latest drivers.

	Still having problemas.  Trying for BBC1 (was hoping to crontab a pipe to 
a file for weekdays at 17:34):


BBC-1:554000000:INVERSION_OFF:BANDWIDTH_8_MHZ:FEC_2_3:FEC_NONE:QAM_64:TRANSMISSION_MODE_2K:GUARD_INTERVAL_1_32:HIERARCHY_NONE:600:601

hashaday@necromancer:~$ tzap  BBC-1
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 554000000 Hz
status 01 | signal 2020 | snr 0000 | ber 0000ffff | unc 00000000 |
status 01 | signal 3131 | snr 0000 | ber 0000ffff | unc 00000000 |


should I be worrying about that signal strength -- my roof aerial feed 
is coming via booster in the attic, maybe it's acting as a bandpass?


hashaday@necromancer:/usr/src/dvb/dvbstream$ ./dvbstream 600 601 -o
dvbstream v0.4pre3 - (C) Dave Chapman 2001
Released under the GPL.
Latest version available from http://www.linuxstb.org/
Output to stdout
Streaming 2 streams


I really had my fingers crossed for a load of gibberish and a corrupted 
console :o\  No hay nada :o(


What I found more worrying is that none the obvious modules were being 
used (I simply used "make insmod"):

	Still, I'm rather scared of the fact that it's using almost 40% of one of 
my Athlons!

	My credit card company will sending a thank you card in the post for the 
tip ;o)  And there was me thinking of buying an XBox (UKP 120 is just 
plain silly) to retrofit into a firewall.


Ho hum, one gadget at a time :o(
