I don't use any Plugins any more :-(

With the -IMHO very important- osdteletext plugin
my DVB-T is unusable.

I don't "see" where the destructors are stopping the threads
or are waiting to finish before releasing the data.


cDevice::~cDevice()
{
  Detach(player);
  for (int i = 0; i < MAXRECEIVERS; i++)
      Detach(receiver[i]);
  delete ciHandler;
  delete nitFilter;
  delete sdtFilter;
  delete patFilter;
  delete eitFilter;
  delete sectionHandler;
}

How are the threads (cleanly) killed which "uses" an receiver?

I don't think that is the cause for the segfault.
It's just an example of the kind of code that makes me wonder ;-) 
learned: It's much easier to start threads than to stop them.
