Ah, I have that as well except on all channels. Recently
found out why: a length of the aerial cable is still in the
old brown cable with a very loose-weave braid. The main CAT5
from my cable modem to my router is a few inches away from
it for about 8ft. I used an extension aerial cable with
modern foil screening to an outlet in another room and
bingo, all was well. All I have to do now is persuade SWMBO
to let me take the floor up to replace the brown cable!

The other possibility that can cause it is too much or too
little signal. All BBC channels are transmitted on a single
mux so the fact that you have no EPG on BBC suggests that
your problem lies with the signal on one frequency.

The TV should be able to show you signal strength somewhere
in its menus. If you are showing a 100% signal on a BBC
channel try fitting an attenuator in the signal feed. You
can either get a fixed 10dB attenuator from Maplin, or a
20dB variable from Screwfix or Toolstation. If you are
showing less than 100% signal then you might need a booster.

It would help all of us on here if you can say roughly where
you are and which transmitter you are using.



Sorry - I didn't make anything clear. I am talking
about Freeview TVs (DTT?). I am in East Lothian so my signals come from
Blackhill or Point of Kelly. When I set up freeview years ago Blackhill
was marginally the stronger.

This is probably a long shot but might be worth checking.

I think your problem can happen if you are receiving the muxes from two
different regions. In your case I guess this might be STV Central and STV
North.

All the Muxes at a transmitter in a single region (or network) carry all the
EPG information for not just that mux but the other muxers as well. So in
theory while you are watching, say ITV, you are still getting the EPG
information for BBC1.

However if you have set your system up, say, so that you have chosen to get
the BBC Mux from a different transmitter to the other muxes, and that BBC
Mux transmitter is in a different region/network to the transmitter for the
other muxes, then, because it is in a different network it will only get the
EPG data for the BBC services when you are tuned to one of those services
and the stored EPG data will probably get discarded when you change to a
service on one of other muxes.

This issue probably only affects, mainly older, receivers that do not check
for reception of multiple regions and give you a choice of preferred region.
From my experience of living on the boundary of two regions older boxes in
these circumstances invariably need careful manual tuning.

So again, as a long shot, it might be worth checking the frequencies for
each of your muxes to make sure they are all coming from the same
transmitter.

As an aside on the discussion about signal strength affecting EPG reception
from my experience the EPG is more robust that the program streams simply
because it is constantly being repeated and errors caused by intermittent
reception will get corrected. I live on the Surrey/Hampshire border and in
the days when Hannigton was not radiating toward Guildford I had hopeless
reception of the services from Hannington but could still get a fully
populated EPG from there.


I hope this is useful,
