In DVBRecorder::SetDemuxFilters(), try adding something like this:

    if (m_pmt.ServiceID == <serviceid of broken channel>)
        OpenFilters(<missing PID>, ES_TYPE_UNKNOWN);

If that works we could simply make it read the sid/pid from the db 
instead, if this is an override that's needed long term...

When was the last time you tried it with Myth 0.16? Maybe the PMT was 
correct then? I'm a bit surprised that it would work with that broken 
PMT, but everything is possible... Do you know if this is a new problem 
or has the PID been missing for long?
