vdr/config.c
Klaus Schmidinger 9384e56566 Version 1.3.6 
- Completed the Finnish OSD texts (thanks to Rolf Ahrenberg).
- Fixed some descriptor handling in 'libsi' (thanks to Stéphane Esté-Gracias).
- Fixed handling the current menu item (thanks to Marc Hoppe).
- Fixed assigning events to timers (they no longer get "stuck").
- Added log entries whenever the running status of an event changes (currently
  only logging the first 30 channels).
- Fixed handling timers in VPS margin if the EPG scan is turned on (the EPG scan
  switched the device away from the channel, so it wouldn't see the change of
  the running status).
- Fixed handling "itemized" texts in EPG data (thanks to Stéphane Esté-Gracias
  for pointing out this problem, and Marcel Wiesweg for improving 'libsi').
- Fixed handling VPS times at year boundaries.
- Avoiding too many consecutive "ring buffer overflow" messages (which only
  slowed down performance even more).
- Taking the Sid into account when detecting version changes in processing the
  PMT (thanks to Stéphane Esté-Gracias for pointing out this problem).
- Completed the Russian OSD texts (thanks to Vyacheslav Dikonov).
- Any newline characters in the 'description' of EPG events are now preserved
  to allow texts to be displayed the way the tv stations have formatted them.
  This was also necessary to better display itemized texts.
- Fixed detecting the running status in case an empty EPG event is broadcast (thanks
  to Michael Pennewiß for pointing this out).
- Improved performance when paging through very long menu lists.
- Removed cSchedule::GetEventNumber() and cSchedule::NumEvents(). There is now
  cSchedule::Events() that returns the list of events directly.
- Avoiding occasional bad responsiveness to user interaction caused by assigning
  events to timers.
- Now explicitly turning on the LNB power at startup, because newer drivers don't
  do this any more (thanks to Oliver Endriss for pointing this out).
