vdr/vdr.c
Klaus Schmidinger bb18b9e0b4 Version 0.94
- Implemented automatic shutdown (see INSTALL and MANUAL for details).
- New SVDRP command NEXT to show the next timer event.
- The new remote control key "Power" can be used to turn the VDR machine
  off (this requires the presence of the '-s' option).
- Fixed code for the default "Ok" button on the PC keyboard (was 0x162 on
  the "good old" keyboards (with the F-keys at the left side), while it changed
  to 0x15E on the newer keyboards).
- When a recording is edited, the summary information (if present) is now
  also copied.
- When a recording is running on the primary interface, any attempt to change
  the current channel will now lead to a "Channel locked" message.
- The main program loop now first checks whether any timer recordings are
  finished, before starting a new timer recording. This is important in case
  one timer ends at the same time another timer starts.
- New setup parameter OSDMessageTime to define how long an OSD message shall
  be displayed.
- The "File" parameter of a timer can now contain the '~' character to store
  the recording in a hierarchical directory structure. The '~' character has
  been chosen since the file system's directory delimiter '/' may be part of
  a regular programme name (showing the directory hierarchy in the "Recordings"
  menu will follow later).
- Repeating timers now create recordings that contain the 'Subtitle' information
  from the EPG data in their file name. Typically (on tv stations that care
  about their viewers) this contains the episode title of a series. The
  subtitle is appended to the timer's file name, separated by a '~' character,
  so that it results in all recordings of this timer being collected in a
  common subdirectory. You can disable this with the 'UseSubtitle' parameter
  in the "Setup" menu.
- The summary information is now taken from the EPG data at the actual time of
  recording (no longer at the time the timer is created in the "Schedule" menu).
  If a timer already has summary data, that data will be used. If you have
  repeating timers in your 'timers.conf', you may want to make sure they do
  NOT contain any summary information (that's the last field in the timer
  definitions). Use your favourite text editor to delete that information.
  That way every recording will store the actual summary data at the time of
  the recording.
