Yet another retune (and it's not working) - Granada region

Am I the only one getting sick of the useless numpties running the UK
Freeview system ? In spite of them claiming that "If you have Sky TV,
Freesat from Sky or freesat on all of your TV sets you will not be
affected by switchover." Today, thanks to their frigging about, the
mux carrying BBC One and BBC Two has moved - so I'm currently
retuning yet again.

For anyone who doesn't know, today, BBC2 analogue was switched off on
the Winter Hill transmitter group (Granada region).

Trouble is, retuning Myth Delete all channels, full scan), it's not
picking up the new mux at all - the other systems in the house have
picked it up OK. It seems to have picked up the transport (ID 4168)
on 801833000Hz, but if I tell it to scan just that transport it says
no signal.

Any ideas ?

Seems that ticking the "Ignore Signal Timeout" setting fixed it.

I'm still not getting all channels. I'm missing Dave, Sky3 etc, basically all the
channels from MUX C. According to this page, which is normally reliable
http://www.ukfree.tv/txdetail.php?a=SD660144

the frequency for that MUX should be 786.2Mhz, but if I force it to be 754Mhz by
changing the mplexid in the channel table, then the channels tune ok.

Manually enerating a channels.conf has the correct frequency listed for these
channels, but after using the channels.conf to create the channels, it ends up with
the wrong frequency again.

I can manually cludge it for now, but I have no idea why this keeps going wrong,
and I'm sick of failed recordings (although given the list of channels on that mux,
I'm not going to lose too much sleep worrying!).

Anyone got any ideas? This has always worked fine before. I make sure I delete all
channels for the source before scanning. Doing a full scan, and a channels.conf
scan have both ended up with invalid frequencies. I have tried the Ignore Signal
TImeout option, to no avail as well.

You could try using the transport editor in mythtv-setup to manually
correct the mux frequency after you have scanned or imported your
channels.conf, and then testing with LiveTV.

A debug option would be to run a full scan after starting mythtv-setup
with 'channelscan, channel, record' verbosity', as the output will
include the mux frequencies that the scanner is seeing during a full
scan.

Cheers,
Nick
