vdr/vdr.c
Klaus Schmidinger 5d8e3b18dc Version 1.4.0-1
- Updated 'S110W' in 'sources.conf'.
- Adjusted the 'runvdr' script so that the user can fill in the functions to
  detect, load and unload the necessary driver modules (thanks to M. Kiesel for
  reporting that it still used DVBDIR).
- Added 'eval' to the $VDRCMD call in 'runvdr' to avoid problems with quoting
  (suggested by Udo Richter).
- Fixed missing ',' in the Italian and Polish OSD texts (thanks to Marko Mäkelä).
- Updated the Czech OSD texts (thanks to Vladimír Bárta).
- Fixed handling the "Power" key in case a timer is about to start recording
  (thanks to Udo Richter).
- Fixed the character 'r' in fontosd and fontsml for iso8859-2 (thanks to Vladimír
  Bárta).
- When checking whether a VPS timer has entered the "VPS margin", the event's start
  time is now used instead of the timer's start time, because otherwise events that
  start way off of their VPS time wouldn't be recorded correctly.
- If VPS timers are active, their events are now being kept up to date if there
  are any free devices available.
- Fixed the character #207 in fontosd for iso8859-2 (thanks to Vladimír Bárta).
- Fixed handling unknown codes when learning LIRC remote control codes (reported
  by Helmut Auer).
- Since some channels (especially the Austrian ORF) randomly change the ids of their
  EPG events, VDR now gives the start time precedence when searching for existing
  events.
- Fixed automatically updating the CAM menu in case the whole operation (for
  instance a firmware update) takes longer than the menu timeout.
