Post by Mal BallRecently I have noticed that there are a number of channels which give a
message in the guide "No data available", additionally BBC1 only ever shows
the current programme and the next program then "No data available"
Anyone know how to fix this? I have tried manually downloading the guide but
this does not work.
MCE2005 at least is notorious for corrupting the guide files and guide
settings, usually this is triggered by a weak DVB-T signal meaning stations
might occasionally not be picked up. When MCE scans for new channels it
loses some due to the poor reception, and they might then reappear next time
but without guide data. That is bad enough and merely entails reconfiguring
what data to show for those channels but I find that over time the files
become so corrupt that it leads to full-blown crashes and eventually the
only option is to completely setup the tuners (and guide) from scratch.
Some channels on DVB-T are weaker than others, in theory they are all coming
from the same transmitter (in my case Crystal Palace), but some stations use
different signalling settings (presumably to allow fitting in more channels)
with a consequence of weaker signals. FiveTV even on DVB-T is for example
weaker than the BBC channels.
On DVB-T channels are in groups (multiplexes) so if there is a problem it
generally affects then entire multiplex, e.g. a bunch of BBC channels, or
the Five channels, or the Channel4 channels.
The first thing to do would be to go back to the guide settings and try
re-adding the guide data to those channels.
There is a registry setting that can allow you to turn off Media Center's
automatic scanning for new channels (this is called "Opportunistic
scanning") and this would prevent it messing up a working setup. You would
then have to manually scan for new channels.
