Hi Nick,

Thanks for the info, sounds like some interesting ideas going forward that
would certainly help this situation.

I have changed the rules to exclude repeat and generic for now, so see how
that works for various shows.  Might change the rule to record just channel
5 for now, then change it back when it starts up again.

Thanks all for help/explanations

Martin
