Comment(by eric.bosch at comcast.net):

 From what I have been able to determine, the backend is getting slammed
 with query's approximately every 50ms, thus causing the delays in handling
 keyboard/remote events.  I don't understand what all the code is doing in
 this area (TVRec::HandlePendingRecordings(void)), the contents of
 'timeuntil' variable never changes.  The next show that is scheduled to
 record is nearly 10 hours from current time, so there appears to be a
 fault in calculation of this value.  The backend is currently using  33%
 of CPU.  The following line in tv_rec.cpp:

 int timeuntil = ((*it).doNotAsk) ? -1:
 QDateTime::currentDateTime().secsTo((*it).recordingStart);

 appears to be the culprit, but I'm not sure how to handle the issue.  I
 will try a couple things and see if I can affect a change, but if somebody
 who understands this part of the code could help direct me, it would be
 immensely appreciated.
