This is probably two different problems. If it saw a PMT but it
didn't match, as indicated by the "WaitForPMT" message, it means
that the the streams are encrypted and cardinput.freetoair is set
to one, or the PMT does not contain both a video and audio stream.
This is debuggable by sticking a pmt->toString() somewhere in
DTVSignalMonitor::SetPMT() and looking at the raw PMT and the
factors listed above.

But we block on events in DVBChannel long before the table monitor is
turned on. If disabling table monitoring is fixing the problem for 
you, then maybe the card doesn't work once you have turned on table
monitoring once. It might be interesting to see if any events are
being sent to the table monitoring file descriptor. It's possible
the tuning events are being sent to the wrong file.

You can stick a return statement as the first statement in 
setup_mpeg_table_monitoring()... for the same effect.
