I have done some more debug on this and the problem is as follows.
Because some channels here in the UK are available both via terrestrial
analog and terrestrial digital TV my channel table in the SQL database has
some entries that have both the "freqid" field and the "mplexid" set. This
used to work, my analog PVR350 card would use the freqid field and my DVB-T
would use the mplexid field.
This is now broken. The DVB multiplex frequency returned from
ChannelUtil::GetTuningParams is used even though the channel is not
associated with a DVB card.
Fixing it is beyond me, I am afraid.
