[linux-dvb] No Lock and no data

["Tim Squires" <nt650@cheekymail.net>]

I've followed the instructions in the MythTV DVB Setup Guide (
http://www.ethics-gradient.net/myth/ ) and everything seemed OK until
testing....

# tzap -r "BBC ONE"
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
reading channels from file '/root/.tzap/channels.conf'
tuning to 690000000 Hz
video pid 0x0258, audio pid 0x0259
status 01 | signal 3131 | snr e1e1 | ber 0000026a | unc 00000000 |
status 1f | signal 3131 | snr e4e4 | ber 00000349 | unc 0000001d |
FE_HAS_LOCK
status 1f | signal 3131 | snr e5e5 | ber 000002b3 | unc 00000000 |
FE_HAS_LOCK
status 1f | signal 3131 | snr e1e1 | ber 000002e5 | unc 00000000 |
FE_HAS_LOCK

ok, no obvious problems there....

and then nothing.

My nearest transmitter is uk-EmleyMoor but dvb-apps/scan could not tune so
I tried the other uk transmitter config files - several of which worked
giving different channel.conf details...
Oxford:BBC

Same frequency, different FEC's.

Could anyone point me in the right direction.  I'm so close to having this
working, I can feel it in my er... bones.

Thanks, Tim
