Version 1.3.19

Browse Source 
- Making sure at least the default skin is available at program start in case a
  plugin needs to issue an error message (thanks to Achim Tuffentshammer for
  reporting a crash in such a case). Also checking if there is a current skin
  in cSkins::Message().
- Completed the Finnish OSD texts and fixed internationalization of the text
  for "Setup/DVB/Audio language(s)" (thanks to Rolf Ahrenberg).
- Completed the Estonian OSD texts and switched to iso8859-13 character set
  (thanks to Arthur Konovalov).
- Made cCondWait::SleepMs() sleep at least 3ms to avoid a possible busy wait.
- Fixed canceling the LIRC thread (thanks to Marco Schlüßler for pointing out
  this one).
- The "Green" button in the "Main" menu is now always "Audio", since the audio
  channel might be changed even if there is only one actual audio PID.
- Fixed handling the '-E' option which was broken in version 1.3.18 (thanks to
  Christian Jacobsen for reporting this one).
- Added 'channels.conf.terr' entries for Mainz (thanks to Michael Heyse).
- Implemented cDolbyRepacker for better handling of Dolby Digital PES packets
  (thanks to Reinhard Nissl).
- Fixed playing files with PES packets longer than 2048 byte through the full
  featured DVB card (thanks to Marco Kremer for reporting this one and providing
  a test sample).
- Recording and Transfer Mode now handle more than 2 audio PIDs. For this the
  interfaces of the following functions have been changed:
  cTransferControl::cTransferControl()
  cTransfer::cTransfer()
  cRecorder::cRecorder()
  cReceiver::cReceiver()
  cRemux::cRemux()
- Fixed a possible race condition in cDevice::Action() and cTSBuffer::Action()
  (thanks to Stefan Huelswitt).
- Extended some buffer sizes to allow handling HDTV streams (thanks to Reinhard
  Nissl).
- Added 'channels.conf.terr' entries for Düsseldorf and Köln (thanks to Walter Koch).
- Falling back to 'stereo' when switching channels in case the user had switched
  to 'left' or 'right' (suggested by Rolf Groppe).
- Completed the Danish OSD texts (thanks to Mogens Elneff).
- Recording and Transfer Mode can now handle up to 8 Dolby Digital tracks (thanks
  to Marco Schlüßler for a patch that implements substream handling into
  cDevice::PlayPesPacket(), and Reinhard Nissl for adding substream handling to
  cDolbyRepacker).
- Added PlayPes(NULL, 0) to cTransfer::Action() when clearing the transfer buffer
  to avoid overflows (thanks to Marco Schlüßler for pointing this out).
