 Negative hits are relevant for all channels that have either been deleted
 or useonairguide disabled though there is some transmitted guide.
 If a multiplex has no channel at all with useonairguide enabled the whole
 multiplex is skipped.

 The patch is untested as of now as I'm running a modified version of the
 EITScanner at the moment.
