[mythtv-users] "Wrong PMT" Is this me, or the broadcaster?

I have had a problem arise in the past 3-4 days with one of the
multiplexers giving "(LMs) Partial Lock" on all of the channels from that
multiplex. As I have made no changes to Mythtv recently I suspect that it
is a problem with this one broadcaster.
My location is regional Australia and we have 5 free-to-air broadcasters
and these are identically from a choice of 2 towers, one operating in the
VHF band and the other in the UHF band.
This particular mux has 3 programs which are identified:
Channel 8 - WIN - sectionid 1
Channel 80 - GEM - sectionid 10
Channel 88 - GO! - sectionid 2
I have deleted these channels and rescanned the mux successfully using
both transitters and the data in the MySQL database is the same as
previous, but when I try to tune any of these 3 channels I get 2 messages
each time in the backend log of the form:
Wrong PMT: pmt->pn(y) preferred (x)
Wrong PMT: pmt->pn(z) preferred (x)
where x matches the correct sectionid above but y and z match the other 2
sectionids above.
Using an independent DVB-T receiver (not Mythtv) I can receive these
channels with no problems.
I suspect that the broadcaster has changed something and whatever it is is
causing Mythtv to barf.
I guess what I really need to know is how to overcome the problem.
TIA.
