vdr/vdr.c
Klaus Schmidinger cd7ccd64fd Version 1.1.13 
- Added cDevice::DeviceNumber() to get the number of a device, not counting any
  gaps that might be in the index count.
- Fixed fetching the current/next information to handle cases where the duration
  of an event is set wrongly and would last beyond the start time of the next
  event.
- Adapted type names to the new HEAD version of the driver (which the previous
  NEWSTRUCT branch has been merged into). Note that to use this driver version
  you still need to add NEWSTRUCT=1 to the make call when building VDR. You
  need a HEAD version of the LinuxDVB driver dated 2002-10-11 or later to compile
  VDR with NEWSTRUCT=1.
- Fixed radio channels in channels.conf.cable (thanks to Robert Schiele and Uwe
  Scheffler).
- Fixed switching the video format in the Setup/DVB menu (thanks to Uwe Scheffler
  for reporting this one).
- Reactivated full handling of second audio PID (even in 'Transfer Mode').
- Fixed a crash when closing down with remote control plugins (thanks to Oliver
  Endriss helping to debug this one).
- Commands in the file 'commands.conf' can now have a '?' at the end of their
  title, which will result in a confirmation prompt before executing the
  command.
- Changed a few leftover 'new char[...]' to MALLOC(char, ...).
- If a command executed from the "Commands" menu doesn't return any output, the
  OSD will now be closed automatically.
- The SVDRP command PUTE now triggers an immediate write of the 'epg.data' file
  (suggested by Gerhard Steiner).
- The new configuration file 'reccmds.conf' can be used to define commands that
  shall be executed from the "Recordings" menu; see MANUAL and 'man vdr(5)' for
  details (suggested by Gerhard Steiner).
